PIN DESCRIPTIONS

PIN #

PIN SYMBOL

PIN DESCRIPTION

Source of high side MOSFET and provides return path for the high side driver.

17-19

Drain of low side MOSFET.

2-3,22,PAD2

23-24,1

Source of low side MOSFET and needs to be connected to power ground.

Drain of high side MOSFET.

21-20,16,PAD1

An internal 5V regulator.A high frequency 4.7uF/X5R ceramic capacitor must be

connected from this pin to the GND pin as close as possible.

5VREG

Voltage supply for internal analog circuit and driver

Voltage supply for the internal 5V regulator.

VCC

VIN

Oscillator's frequency can be set by using an external resistor from this pin to

GND.

Ground.

GND

This pin is the output of the error amplifier and is used to compensate the voltage

control feedback loop. This pin is also used as a shut down pin. When this pin is

pulled below 0.3V, both drivers are turned off and internal soft start is reset.

COMP

This pin is the error amplifier inverting input. This pin is connected via resistor

divider to the output of the switching regulator to set the output DC voltage.

BST

OCP

This pin supplies voltage to the high side driver. A high frequency

ceramic capacitor of 0.1 to 1uF must be connected from this pin to SW pin.

This pin is connected to the D2 of the low side MOSFET and is the input of the

over current protection(OCP) comparator. An fixed internal current flows to the

external resistor which sets the OCP voltage across the Rdson of the low side

MOSFET. Current limit point is this voltage divided by the Rds-on.

Not used pin. Connecting these pins to ground is recommended.
