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.
