1, 2

Input Voltage.

EN

3

Enable Input, Active High.

SS

4

Soft-Start Adjust. An external capacitor connected to this pin will set the ramp-up time of VOUT.

PG

5

Power Good. Open-drain output to indicate when the switch is fully enhanced.

DIS

6

Output Discharge. An external resistor between DIS and VOUT sets the discharge rate at VOUT

when EN goes low.

VOUT
