PIN NAME

DESCRIPTION

1, 2

Output Voltage. These pins are Power-switch output.

3

OC#

Fault Flag. Open-drain output, to report overcurrent or over-temperature conditions..

4

S3#

Sleep State Control Pin. This pin along with the 5VCC status controls the switching

configuration.

5

EN

Enable Input. Logic high turns on power switch.

6

GND

Ground.

7

5VSB

Supply Input. This pin is the N-Channel MOSFET Drain that supplies output current at

S3/S4/S5 states and should be connected to 5VSB.

8

Supply Input from 5VCC. This pin is the N-Channel MOSFET Drain that supplies output

current at S0/S1/S2 states and should be connected to 5VCC.
