DN05022 Datasheet (ON Semiconductor)

DN05022, Low-Cost LED Dimming

This circuit can be thought of as having two separate portions.

There is an LED management portion and a dimmer management/PWM Signal portion.

The LED management portion charges the output capacitor to run the LEDs in a “DC” state.

The dimmer management portion provides loading current for the TRIA
