Pin Name

Function

Switch pin. Connect external inductor and Schottky

GND

Ground

Voltage feedback. Reference voltage is 200mV

CTRL

Enable and dimming control pin. Connect to a high input to enable

the IC or a low input to disable the IC. Connect to a PWM input to

achieve dimming control If logic low time is less than about 0.7

ms, AP3032 is hold on standby mode, at which it shut down the

power switch but shield the soft-start function, to achieve high

frequency dimming

Over voltage protection input. Connect to the output directly. On

OVP condition, the output voltage will clamp

VIN

Input supply pin. Must be locally bypassed
