General Description

The HV9961 is an Average-Current mode
constant-current control LED driver IC operating in a
constant Off-time mode. Unlike the HV9910B, this
control IC does not produce a peak-to-average error.
This greatly improves accuracy as well as the line and
load regulations of the LED current without any need
for loop compensation or high-side current sensing. Its
output LED current accuracy is ±3%.

The IC is equipped with a current limit comparator for

mode output short-circuit protection.

The HV9961 can be powered from an 8V–450V supply.

has a PWM dimming input that accepts an external

It
control TTL-compatible signal. In addition, the output
current can be programmed by an internal 275 mV
reference or controlled externally through a 0V–1.5V
linear dimming input.

The HV9961 is pin-to-pin compatible with HV9910B,

d it can be used as a drop-in replacement for many

an
applications to improve LED current accuracy and
regulation.

3.0 APPLICATION INFORMATION

3.1 General Description

Peak current control (as in HV9910B) is the simplest
and the most economical way to regulate a buck
converter's output current. However, it suffers accuracy
and regulation problems that arise from
peak-to-average current error, contributed by the
current ripple in the output inductor and the
propagation delay in the current sense comparator.
The full inductor current signal is unavailable for direct
switch current sensing across the sense resistor at the
ground path in this low-side switch buck converter
when the control switch is at the ground potential
because the switch is turned off. While it is very simple
to detect the peak current in the switch, controlling the
average inductor current is usually implemented by
level translating the sense signal from +V
this is practical for a relatively low-input voltage, VIN,
this type of average-current control may become
excessively complex and expensive in the offline AC or
other high-voltage DC applications.

The HV9961 uses a proprietary

control scheme that
allows fast and accurate control of the average current
in the buck inductor by sensing the switch current only.
No compensation of the current control loop is
required. The output LED current’s response to PWMD
input is similar to that of the HV9910B. The effect of
inductor current ripple amplitude on this control
scheme is insignificant. Therefore, the LED current is
independent of the variation in inductance, switching
frequency or output voltage. Constant off-time control
of the buck converter is used for stability and improving
the LED current regulation over a wide range of input
voltages. Unlike HV9910B, the HV9961 does not

ort Constant Frequency mode.

3.3 Average-Current Control Feedback and Output Short-circuit Protection

The current through the switching Metal-oxide
Semiconductor Field-effect Transistor (MOSFET)
source is averaged and used to give constant-current
feedback. This current is detected with a sense resistor
at the CS pin. The feedback operates in a fast
Open-loop mode. No compensation is required. Output
current is programmed as seen in Equation 3-2.

EQUATION 3-2:

If the voltage at the LD input is less than 1.5V, the
output current is computed as specified in

Equation 3-3.

EQUATION 3-3:

The above equations are only valid for continuous
conduction of the output inductor. It is good design
practice to choose the inductance of the inductor such
that the peak-to-peak inductor current is 30% to 40% of
the average DC full-load current. Hence, the
recommended inductance can be calculated as shown
in Equation 3-4.

EQUATION 3-4:

3.2 Off Timer

The timing resistor connected between RT and GND
determines the off-time of the gate driver. Wiring this
resistor between RT and Gate as with HV9910B is no
longer supported. Refer to Equation 3-1 for the

ation of the gate output’s off-time.

3.4 Linear Dimming

When the voltage at LD falls below 1.5V, the internal
275 mV reference to the constant-current feedback
becomes overridden by VLD x 0.185. As long as the
current in the inductor remains continuous, the LED
current is given by Equation 3-3. However, when V
falls below 150 mV, the gate output becomes disabled.
The gate signal recovers when V

exceeds 200 mV. It

The linear dimming input could also be used for
“mixed-mode” dimming to expand the dimming ratio. In
such case, a pulse-width modulated signal with an
amplitude below 1.5V should be applied to LD.

3.5 Input Voltage Regulator

The HV9961 can be powered directly from an
8 VDC–450 VDC supply through its VIN input. When this
voltage is applied at the VIN pin, the HV9961 maintains
a constant 7.5V level at V
to power the IC and external circuitry connected to V
within the rated maximum current or within the thermal
ratings of the package, whichever limit is lower. The

pin must be bypassed by a low ESR capacitor to

DD

provide a low-impedance path for the high-frequency
current of the gate output. The HV9961 can also be

wered through the VDD pin directly with a voltage

po
greater than the internally regulated 7.5V, but less than
12V.

Despite the instantaneous voltage rating of 450V,

uous voltage at VIN is limited by the power

contin
dissipation in the package. For example, when HV9961
draws I

= 2.5 mA from the VIN input, and the 8-pin

IN

SOIC package is used, the maximum continuous
voltage at VIN is limited to the value shown in

Equation 3-5.

3.7 PWM Dimming

Due to the fast open-loop response of the
average-current control loop of the HV9961, its PWM
dimming performance nearly matches that of the
HV9910B. The inductor current waveform comparison
is shown in Figure 3-4.

FIGURE 3-4: Typical PWM Dimming Response of an HV9961 LED Driver.

The rising and falling edges are limited by the current
slew rate in the inductor. The first switching cycle is
terminated upon reaching the 275 mV or V
level at CS. The circuit is further reaching its
steady-state within 3–4 switching cycles regardless of
the switching frequency.

NG = 16-lead SOIC

Environmental: G = Lead (Pb)-free/RoHS-compliant Package

Media Types: (blank) = 3300/Reel for an LG Package

(blank) = 45/Tube for an NG Package

M901 = 2600/Reel for an NG Package

M934 = 2600/Reel for an NG Package

Note: For Media Types M901 and M934, the base quantity for tape and reel

was standardized to 2600/reel. Both options will result in the delivery of
the same number of parts/reel.

Note the following details of the code protection feature on Microchip devices:

YSTEM 

CERTIFIEDBYDNV

== ISO/TS16949==

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
