Description

AUX

1

Enable for the auxiliary output voltage

VIN

2

Input supply voltage. Bypass this pin to ground with a 10 μF capacitor

SW

3

Switching output. Inductor connection

GND

4

Ground

VOUT

5

Sense pin used to monitor output voltage

Vout2

6

Auxiliary output pin with OCP (100 mA max. load)

PGOOD

7

Open drain output. It is in high impedance when the output regulation reaches 97%

CL

8

Current limit set. Connect to GND sets the default value (700 mA). An external resistor connected to

GND can be used to adjust this parameter with a lower value (resistor values are reported on
