Dimming LEDs looks simple at first sight. Grab a PWM output from some microcontroller, pass it through a power FET and Bob's your uncle. In this article, focus is on another architecture - not new at all, but often overlooked - that delivers top quality LED flicker performance and quality dimming while maintaining efficiency. The circuit is implemented using standard components, making it suitable for educational purposes.
