Pin Descriptions

Pin

Pin Name

Pin Function



CS

Current sense input (negative)

2

VIN

Device supply voltage (also positive current sense input)

3

GATE

PWM gate driver output for boost converter

4

GND

Device ground

5

SS/VREF

Soft start and reference voltage pin

6

FB

Error amplifier inverted input

7

OCP/EN

When a capacitor is tied to this pin, the maximum inrush current is controlled during start-up. The capacitor value

also determines the off-time after the device has entered hiccup mode. Pulling this pin low can disable the linear

and the switcher to turn off the circuit.

8

DRV

Gate drive of input disconnect FET limiting system input current
