With a 40-V rated integrated switch FET, the
TPS61160A/61A is a boost converter that drives
LEDs in series. The boost converter runs at 600-kHz
fixed switching frequency to reduce output ripple,
improve conversion efficiency, and allows for the use
of small external components.

The default white LED current is set with the external
sensor resistor Rset, and the feedback voltage is
regulated to 200 mV, as shown in the typical
application. During the operation, the LED current can
be controlled by a pulse width modulation (PWM)
signal applied to the CTRL pin through which the duty
cycle determines the feedback reference voltage. In
PWM dimming mode, the TPS61160A/61A does not
burst the LED current; therefore, it does not generate
audible noises on the output capacitor. For maximum
protection, the device features integrated open LED
protection that disables the TPS61160A/61A to
prevent the output from exceeding the absolute
maximum ratings during open LED conditions.

The TPS61160A/61A is available in a space-saving,
2-mm × 2-mm WSON package with thermal pad.

7 Detailed Description

7.1 Overview

The TPS61160A/61A is a high-efficiency, high output voltage boost converter in small package size that is ideal
for driving white LED in series. The serial LED connection provides even illumination by sourcing the same
output current through all LEDs, eliminating the need for expensive factory calibration. The device integrates 40­V/0.7-A switch FET and operates in pulse width modulation (PWM) with 600-kHz fixed switching frequency. For
operation see the block diagram. The duty cycle of the converter is set by the error amplifier output and the
current signal applied to the PWM control comparator. The control architecture is based on traditional current­mode control; therefore, a slope compensation is added to the current signal to allow stable operation for duty
cycles larger than 50%. The feedback loop regulates the FB pin to a low reference voltage (200 mV typical),
reducing the power dissipation in the current sense resistor.

7.2 Functional Block Diagram

7.3 Feature Description

7.3.1 Soft Start-Up

Soft-start circuitry is integrated into the IC to avoid a high inrush current during start-up. After the device is
enabled, the voltage at FB pin ramps up to the reference voltage in 32 steps, each step takes 213 μs. This
ensures that the output voltage rises slowly to reduce the input current. Additionally, for the first 5 msec after the
COMP voltage ramps, the current limit of the switch is set to half of the normal current limit spec. During this
period, the input current is kept below 400 mA (typical). See the start-up waveform of a typical example,

Feature Description (continued)

7.3.2 Open LED Protection

Open LED protection circuitry prevents IC damage as the result of white LED disconnection. The
TPS61160A/61A monitors the voltage at the SW pin and FB pin during each switching cycle. The circuitry turns
off the switch FET and shuts down the IC when both of the following conditions persist for 8 switching clock
cycles: (1) the SW voltage exceeds the V
voltage. As a result, the output voltage falls to the level of the input supply. The device remains in shutdown
mode until it is enabled by toggling the CTRL pin logic. To allow the use of inexpensive low-voltage output
capacitor, the TPS61160A/61A has different open lamp protection thresholds. The threshold is set at 26 V for the
TPS61160A and 38 V for the TPS61161A. Select the appropriate device so that the product of the number of
external LEDs and each LED's maximum forward voltage plus the 200 mV reference voltage does not exceed
the minimum OVP threshold or (n

LEDS

X V

7.3.3 Shutdown

The TPS61160A/61A enters shutdown mode when the CTRL voltage is logic low for more than 2.5 ms. During
shutdown, the input supply current for the device is less than 1 μA (max). Although the internal FET does not
switch in shutdown, there is still a DC current path between the input and the LEDs through the inductor and
Schottky diode. The minimum forward voltage of the LED array must exceed the maximum input voltage to
ensure that the LEDs remain off in shutdown; however, in the typical application with two or more LEDs, the
forward voltage is large enough to reverse bias the Schottky and keep leakage current low.

7.3.4 Current Program

The FB voltage is regulated by a low 0.2-V reference voltage. The LED current is programmed externally using a
current-sense resistor in series with the LED string. The value of the RSET is calculated using Equation 1:

threshold and (2) the FB voltage is less than half of regulation

where

• I

• VFB= regulated voltage of FB

• R

LED

= current sense resistor (1)

SET

The output current tolerance depends on the FB accuracy and the current sensor resistor accuracy.

7.3.5 PWM Brightness Dimming

When the CTRL pin is constantly high, the FB voltage is regulated to 200 mV typically. However, the CTRL pin
allows a PWM signal to reduce this regulation voltage; therefore, it achieves LED brightness dimming. The
relationship between the duty cycle and FB voltage is given by Equation 2.

where

• Duty = duty cycle of the PWM signal

• 200 mV = internal reference voltage (2)

As shown in Figure 11, the IC chops up the internal 200-mV reference voltage at the duty cycle of the PWM
signal. The pulse signal is then filtered by an internal low pass filter. The output of the filter is connected to the
error amplifier as the reference voltage for the FB pin regulation. Therefore, although a PWM signal is used for
brightness dimming, only the WLED DC current is modulated, which is often referred as analog dimming. This
eliminates the audible noise which often occurs when the LED current is pulsed in replica of the frequency and
duty cycle of PWM control. Unlike other scheme which filters the PWM signal for analog dimming,
TPS61160A/61A regulation voltage is independent of the PWM logic voltage level which often has large
variations.

For optimum performance, use the PWM dimming frequency in the range of 5 kHz to 100 kHz. The requirement
of minimum dimming frequency comes from the output ripple. Low frequency causes high output ripple. Since the
CTRL pin is logic only pin, applying an external RC filter to the pin does not work.

To use lower PWM dimming, add an external RC network connected to the FB pin as shown in Figure 15).

7.3.6 Undervoltage Lockout

An undervoltage lockout prevents operation of the device at input voltages below typical 2.2 V. When the input
voltage is below the undervoltage threshold, the device is shutdown and the internal switch FET is turned off. If
the input voltage rises by undervoltage lockout hysteresis, the IC restarts.

7.3.7 Thermal Shutdown

An internal thermal shutdown turns off the device when the typical junction temperature of 160°C is exceeded.
The device is released from shutdown automatically when the junction temperature decreases by 15°C.

When the CTRL pin is held below the VIL threshold, the device is disabled, and switching is inhibited. The IC
quiescent current is reduced in this state. When VINis above the UVLO threshold, and the CTRL terminal is
increased above the VIH threshold the soft-start sequence initiates then the device becomes active.

7.4.2 External PWM Dimming

For assistance in selecting the proper values for Rset, R1-R3, RFLTR, CFLTR and D2 for the specific
application, refer to How to Use Analog Dimming With the TPS6116x (SLVA471) and/or Design Tool for Analog
Dimming Using a PWM Signal (http://www.ti.com/lit/zip/slvc366). Also see Choosing Component Values section

Applying Equation 3 and Equation 4, when VINis 3 V, 10 LEDs output equivalent to V

of 32.2 V, the inductor

OUT

is 22 μH, the Schottky forward voltage is 0.2 V, the maximum output current is 47 mA in typical condition.

8.2.1.2 Detailed Design Procedure

8.2.1.2.1 Maximum Output Current

The overcurrent limit in a boost converter limits the maximum input current, and thus maximum input power for a
given input voltage. Maximum output power is less than maximum input power due to power conversion losses.
Therefore, the current limit setting, input voltage, output voltage and efficiency can all change maximum current
output. The current limit clamps the peak inductor current; therefore, the ripple has to be subtracted to derive
maximum DC current. The ripple current is a function of switching frequency, inductor value and duty cycle.

Equation 3 and Equation 4 take into account of all the above factors for maximum output current calculation.

where

• Ip= inductor peak to peak ripple

• L = inductor value

• Vf= Schottky diode forward voltage

• Fs = switching frequency

• V

= output voltage of the boost converter. It is equal to the sum of VFB and the voltage drop across LEDs

8.2.1.2.2 Inductor Selection

= maximum output current of the boost converter

out_max

= over current limit

lim

The selection of the inductor affects steady state operation as well as transient behavior and loop stability. These
factors make it the most important component in power regulator design. There are three important inductor
specifications, inductor value, DC resistance and saturation current. Considering inductor value alone is not
enough.

The inductor value determines the inductor ripple current. Choose an inductor that can handle the necessary
peak current without saturating, according to half of the peak-to-peak ripple current given by Equation 3, pause
the inductor DC current given by:

(5)

Inductor values can have ±20% tolerance with no current bias. When the inductor current approaches saturation
level, its inductance can decrease 20% to 35% from the 0A value depending on how the inductor vendor defines
saturation current. Using an inductor with a smaller inductance value forces discontinuous PWM when the
inductor current ramps down to zero before the end of each switching cycle. This reduces the boost converter’s
maximum output current, causes large input voltage ripple and reduces efficiency. Large inductance value
provides much more output current and higher conversion efficiency. For these reasons, a 10 μH to 22 μH
inductor value range is recommended. A 22 μH inductor optimized the efficiency for most application while
maintaining low inductor peak to peak ripple. Table 2 lists the recommended inductor for the TPS61160A/61A.
When recommending inductor value, the factory has considered –40% and +20% tolerance from its nominal
value.

TPS61160A/61A has built-in slope compensation to avoid sub-harmonic oscillation associated with current mode
control. If the inductor value is lower than 10 μH, the slope compensation may not be adequate, and the loop can
be unstable. Therefore, customers need to verify the inductor in their application if it is different from the
recommended values.

The high switching frequency of the TPS61160A/61A demands a high-speed rectification for optimum efficiency.
Ensure that the diode average and peak current rating exceeds the average output current and peak inductor
current. In addition, the diode’s reverse breakdown voltage must exceed the open LED protection voltage. The
ONSemi MBR0540 and the ZETEX ZHCS400 are recommended for TPS61160A/61A.

8.2.1.2.4 Compensation Capacitor Selection

The compensation capacitor C3 (see Functional Block Diagram), connected from COMP pin to GND, is used to
stabilize the feedback loop of the TPS61160A/61A. Use a 220-nF ceramic capacitor for C3.

8.2.1.2.5 Input and Output Capacitor Selection

The output capacitor is mainly selected to meet the requirements for the output ripple and loop stability. This
ripple voltage is related to the capacitor’s capacitance and its equivalent series resistance (ESR). Assuming a
capacitor with zero ESR, the minimum capacitance needed for a given ripple can be calculated by

where

• V

= peak-to-peak output ripple (6)

ripple

The additional output ripple component caused by ESR is calculated using:

(7)

Due to its low ESR, Vripple_ESR can be neglected for ceramic capacitors, but must be considered if tantalum or
electrolytic capacitors are used.

Care must be taken when evaluating a ceramic capacitor’s derating under dc bias, aging and AC signal. For
example, larger form factor capacitors (in 1206 size) have a resonant frequencies in the range of the switching
frequency. So the effective capacitance is significantly lower. The DC bias can also significantly reduce
capacitance. Ceramic capacitors can loss as much as 50% of its capacitance at its rated voltage. Therefore,
leave the margin on the voltage rating to ensure adequate capacitance at the required output voltage.

The capacitor in the range of 1 μF to 4.7 μF is recommended for input side. The output requires a capacitor in
the range of 0.47 μF to 10 μF. The output capacitor affects the loop stability of the boost regulator. If the output
capacitor is below the range, the boost regulator can potentially become unstable. For example, if use the output
capacitor of 0.1 μF, a 470 nF compensation capacitor has to be used for the loop stable.

The popular vendors for high value ceramic capacitors are:

8.2.2.2 Detailed Design Procedure

8.2.2.2.1 Choosing Component Values

As per SLVA471, the values of R

FLTR

, C

, R1, R2, and R

FLTR

are determined by the system parameters and

SET

error tolerance. The main source of LED current error is leakage current from the FB pin. The error gets worse
as the LED current decreases. The error due to leakage current is given by Functional Block Diagram, where the
impedance seen by the FB pin has a major impact. To reduce error due to the leakage current, the impedance
seen by the FB pin needs to be small. Because R2is much smaller than R1+ R

, R2must be chosen to be

FLTR

small to minimize the impedance seen by the FB pin. In general, R2must be chosen to be 1 kΩ or less. If greater
accuracy at smaller currents is needed, then R2must be chosen to be even smaller.

(8)

Once R2has been chosen, the value of R

Equation 11, and Equation 12. The individual values of R1and R

+ R

. In general, choosing R1and R

FLTR

FLTR

and R1+ R

SET

can be calculated using Equation 9, Equation 10,

FLTR

can be any combination that sums up to R

FLTR

to be the same value gives a minimum requirement for C

FLTR

.

(9)

(10)

1

(11)

(12)

Finally, C
is popular in many lighting products. At a minimum, C

can be chosen based on the amount of filtering desired or to provide a gradual dimming effect that

FLTR

must be chosen to provide at least 20 dB of

FLTR

attenuation at the PWM frequency. Equation 13 can be used to calculate the minimum capacitor value to provide
this attenuation.

(13)

To provide gradual dimming, a large capacitor must be chosen to provide a long transient time when changing
the PWM duty cycle. Equation 14 shows how to calculate the recommended corner frequency of the RC filter
based on the 10% to 90% rise time. Once the corner frequency is known, it can be used to calculate the required
capacitor using Equation 15.

(14)

(15)

For example, a design with R

and R1equal to 10 kΩ and a desired rise time of 500 ms requires a corner

FLTR

frequency of 0.7 Hz and a capacitor of 47 μF.

10 Layout

10.1 Layout Guidelines

As for all switching power supplies, especially those high frequency and high current ones, layout is an important
design step. If layout is not carefully done, the regulator could suffer from instability as well as noise problems.
To reduce switching losses, the SW pin rise and fall times are made as short as possible. To prevent radiation of
high frequency resonance problems, proper layout of the high frequency switching path is essential. Minimize the
length and area of all traces connected to the SW pin and always use a ground plane under the switching
regulator to minimize inter-plane coupling. The loop including the PWM switch, Schottky diode, and output
capacitor, contains high current rising and falling in nanosecond and should be kept as short as possible. The
input capacitor needs not only to be close to the VIN pin, but also to the GND pin in order to reduce the IC
supply ripple. Figure 27 shows a sample layout.

10.2 Layout Example

Figure 27. Sample Layout

10.3 Thermal Considerations

The maximum IC junction temperature should be restricted to 125°C under normal operating conditions. This
restriction limits the power dissipation of the TPS61160A/61A. Calculate the maximum allowable dissipation,
P

, and keep the actual dissipation less than or equal to P

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation

of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
