Pin Functions

PIN I/O DESCRIPTION
NAME NO.
COMP 1 I/O Compensation pin
FB 2 I Feedback pin
EN 3 I Shutdown control input. Connect this pin to logic high level to enable the device
AGND 4 — Analog ground
PGND 5 — Power ground
SW 6, 7 I Switch pin
IN 8 I Input supply pin
FREQ 9 I Frequency select pin. The power switch operates at 650 kHz if FREQ is connected to GND and at 1.2 MHz if FREQ is connected to IN.
SS 10 O Soft-start control pin. Connect a capacitor to this pin if soft start is needed. Open = no soft start
Thermal Pad — Ground
