PIN DESCRIPTION

PIN #

NAME

FUNCTION

1, 2

VIN

Power switch input pins; two pins are fused inside the package

3

SS

A capacitor from this pin to GND sets output voltage slew rate

4

EN / UVLO

Active high switch control input; VTHL < 0.3 V, VTHH > 1.4 V

5ILIM / IMON

A resistor from this pin to GND sets the overload and short-circuit current limit; the pin can be used

for current reporting, referring to the voltage developed over the current limit setting resistor

6

GND

Ground

7OVP

Input for setting the programmable overvoltage protection threshold. An overvoltage event

turns-off the internal FET and asserts FLT to indicate the overvoltage fault

8PGD

Open drain output, when VOUT is  95 % VIN, and none of the following faults are triggered:

OT, OC, OV

9, 10

VOUT

Power switch output pins; two pins are fused inside the package

Exposed pad

GND

The package’s central exposed pad must be connected to the ground plane; optimal PCB thermal

design will enhance device performance
