XC9135/XC9136 Series

1A Driver Transistor Built-In, Multi Functional Step-Up DC/DC Converters

■GENERAL DESCRIPTION

XC9135/XC9136 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-channel driver transistor and a 0.2 Ω(TYP.) synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors. The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a 33 Ωload resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery. During the operation of a shutdown, the load disconnection function enables to cut the current conduction path from the input to the output. The output voltage is selectable in 0.1V increments within 1.8~5.0V (±2.0% accuracy).

The UVLO function of the XC9135 series is capable to reduce leaking potassium hydroxide by stopping IC operation while

battery voltage is declining. The release voltages of UVLO are 0.85V (±6.0% accuracy) and 1.6V (±3.0% accuracy), and

selectable voltages range of 0.9V~3.0V.

A capacitor can be connected to the CDF pin to set the delay time for stopping operation after UVLO is detected. The length of

the delay time depends on the capacitance of the Cdf capacitor. Use a capacitor with a capacitance of 1000pF or higher for the Cdf capacitor.

The relationship between the capacitance of the Cdf capacitor and the delay time is 1 ms of delay for each 1000pF (3000pF

■OPERATIONAL EXPLANATION (Continued)

The XC9135/XC9136 series consists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, N-channel driver transistor, P-channel synchronous rectification switching transistor and current limiter circuit.

The error amplifier compares the internal reference voltage with the resistors RFB1 and RFB2. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time of the N-channel driver transistor during PWM operation. The PWM comparator compares, in terms of voltage level, the signal from the error amplifier with the ramp wave from the ramp wave circuit, and delivers the resulting output to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure stable output voltage. The current feedback circuit monitors the N-channel driver transistor’s turn-on current for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when a low ESR capacitor, such as a ceramic capacitor, is used, ensuring stable output voltage.

The source provides the reference voltage to ensure stable output of the DC/DC converter.

The ramp wave circuit determines switching frequency. The frequency is fixed internally at 1.2MHz. The Clock generated is used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits.

The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the feedback voltage divided by the internal resistors (R of the error amplifier increases. The gain and frequency characteristics of the error amplifier are optimized internally.

■OPERATIONAL EXPLANATION (Continued)

< Maximum Current Limit>

The current limiter circuit monitors the maximum current flowing through the N-channel driver transistor connected to the Lx pin, and features a combination of the current limit and latch function.

① When the driver current is greater than a specific level (equivalent to peak coil current), the maximum current limit

function starts to operate and the pulses from the Lx pin turn off the N-channel driver transistor at any given time. When the driver transistor is turned off, the limiter circuit is then released from the maximum current limit detection state.

②

③ At the next pulse, the driver transistor is turned on. However, the transistor is immediately turned off in the case of

an over current state.

④ When the over current state is eliminated, the IC resumes its normal operation.

The XC9135 series waits for the over current state to end by repeating the steps ① through ③.

If an over current state continues for several milliseconds and the above three steps are repeatedly performed, the IC performs the function of latching the OFF state of the N-channel driver transistor and P-channel synchronous transistor, and goes into operation suspension mode. After being put into suspension mode, the IC can resume operation by turning itself off once and then re-starting via the EN pin, or by restoring power to the V

IN pin.

The XC9136 series does not have this latch function, so operation steps ① through ③ repeat until the over current state

ends. Integral latch time may be released from an over current detection state because of the noise. Depending on the state of a substrate, it may result in the case where the latch time may become longer or the operation may not be latched. Please locate an input capacitor as close as possible.

Please note that the current flow into the N-channel driver transistor is different from output current I

For protection against heat damage, the thermal shutdown function monitors chip temperature. When the chip’s

temperature reaches 150

O

C (TYP.), the thermal shutdown circuit starts operating and the driver transistor will be turned off. At the same time, the output voltage decreases. When the temperature drops to 130 flow, the IC performs the soft start function to initiate output startup operation.

<MODE>

The MODE pin operates in PWM mode by applying a high level voltage and in PFM/PWM automatic switching mode by

applying a low level voltage.

<Shut-Down, Load Disconnection Function>

The IC enters chip disable state by applying low level voltage to the EN pin. At this time, the N-channel and P-channel synchronous switching transistors are turned OFF. Please also note that a parasitic diode of the P-channel synchronous switch is controlled, thus, the current conduction path is disconnected.

The FO pin becomes high impedance during over current state, over temperature state, soft-start period, and shut-down period. In normal state, the FO pin is low impedance. The FO pin is N-channel open drain output.

The XC9135 Series has a UVLO function. When the voltage of the BAT pin falls below V

On the XC9135 Series, a capacitor Cdf can be connected to the CDF pin to set the delay time for stopping operation after

UVLO is detected.

This will prevent malfunctioning of the UVLO function due to temporary drops in the BAT voltage caused by load transients

and other conditions.

If the BAT voltage falls below the UVLO detection voltage and then returns to the UVLO release voltage or higher within the

detection delay time, the IC will continue operating.

If the BAT voltage does not return to the UVLO release voltage or higher within the detection delay time, the IC will stop

oscillating after the detection delay time has elapsed.

■NOTE ON USE

1. Please do not exceed the stated absolute maximum ratings values.

2. The DC/DC converter performance is greatly influenced by not only the ICs' characteristics, but also by those of the external components. Care must be taken when selecting the external components. Especially for CL load capacitor, it is recommended to use type B capacitors (JIS regulation) or X7R, X5R capacitors (EIA regulation).

3. Make sure that the PCB GND traces are as thick and wide as possible. The ground voltage fluctuation caused by high ground current at the time of switching may result in instability of the IC. Therefore, the GND traces close to PGND pin and AGND pin are important.

4. Please mount each external component as close to the IC as possible. Also, please make traces thick and short to reduce the circuit impedance.

5. When the device is used in high step-up ratio, the current limit function may not work during excessive load current. In this case, the maximum duty cycle limits maximum current. For the XC9135 series, while the current is controlled with maximum duty cycle, over current latch function will not work.

6. In case of connecting to another power supply as shown in below circuit diagram, please use the XC9135C/XC9135K/XC9135M/XC9135T/XC9136N series. Please also note that the MODE pin is fixed in low level for selecting PWM/PFM auto mode. If the MODE pin is in high to maintain fixed PWM control mode, the backflow current may happen. If the output of XC9135A/XC9135B/XC9135L/XC9135R/XC9136E series is connected to another power supply, the IC may be damaged.

7. The maximum current limiter controls the limit of the N-channel driver transistor by monitoring current flow. This function does

not limit the current flow of the P-channel synchronous transistor. When over current flows to the P-channel synchronous transistor in case of load, the IC may be damaged.

8. The integral latch time of the XC9135 series could be released from the maximum current detection state as a result of board

mounting conditions. This may extend integral latch time or the level required for latch operation to function may not be reached. Please connect the output capacitor as close to the IC as possible.

9. The MODE pin and EN pin are not pulled-down internally. Please make sure that the voltage applied to the MODE pin and

the EN pin.

10. When used in small step-up ratios, the device may skip pulses during PWM control mode.

11. In the PWM/PFM auto, transition from PFM to PWM mode, or PWM to PFM mode, the output voltage may be fluctuated.

When the MODE pin is tied to low, the current flows into the parasitic diode of the P-channel synchronous transistor so that results in generating excessive heat in the IC. Please test in the board before usage with considering heat dissipation. For the XC9135A /XC9135B/XC9135L/XC9135R/XC9136E, series (under development) the P-channel synchronous transistor is always turned on which is no matter of MODE pin control.

2. Please mount each external component as close to the IC as possible.

3. Place external components as close to the IC as possible and use thick and short traces to reduce the circuit impedance.

4. Make sure that the PCB GND traces are thick and wide as possible. Ground voltage level fluctuation created by high

ground current at the time of switching may cause instability of the IC.

5. The internal driver transistors bring on heat because of the I
