Pin Description
Pin Number Pin Name Function
1 SW Switch pin. Connect external inductor and Schottky
2 GND Ground
3 FB Voltage feedback. Reference voltage is 200mV
4 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
5 OV
Over voltage protection input. Connect to the output directly. On
OVP condition, the output voltage will clamp
6 VIN Input supply pin. Must be locally bypassed
