APPLICATION NOTE 4708
LED driver solution for MR16 and similar retrofit lamps
By: Piero Bianco


Abstract: This application note presents an LED driver solution for MR16 and similar retrofit lamps. The circuit drives LEDs from a
12VAC input. The solution works with both magnetic and electronic transformers and is dimmable. It requires no electrolytic
capacitors, which extends LED lamp life. Test setup and results are shown.


Introduction
This application note describes a proprietary solution that will drive LEDs off a 12VAC input for MR16 and similar retrofit lamps.
This design can be used with both m
