PIN NAME

DESCRIPTION

1

EN

soft-start process. The EN pin is pulled high internally, hence it can be left open if the

EN control is not used.

2

GND

Ground pin of the circuitry. All voltage levels are measured with respect to this pin.

3

FB

Voltage Feedback Pin. Connecting this pin to an external resistor divider receives the

feedback voltage of the regulator.

4

SS

Connect this pin to a capacitor for soft-start.

5

DRV

This pin drives the gate of an external N-channel MOSFET for linear regulator.

6

Power input pin of the device. The voltage at this pin is monitored for

Power-On-Reset purpose.
