PIN FUNCTIONS

QFN-12

(2mmx2mm)

Pin #

Name Description

1

EN

Enable Input. Pulling this pin below the specified threshold shuts the chip down.

2

GND Ground.

3

VCC Supply Voltage to the Control Circuitry.

4

ILIM

Output Current Limit Configure. Place a resistor to ground to set the overload current limit

level.

5

SS

Soft Start Pin. An external capacitor connected to this pin sets the slew rate of the output

voltage soft start period.

6, 11

VIN

Input Power Supply.

7, 8, 9, 10

VOUT Output to the Load.

12

PG

Power Good Pin. Push-Pull output to monitor input voltage. If VIN pin voltage is higher than

3V, the PG voltage is high.
