AN874 Buck Configuration High-Power LED Driver

AN874 Buck Configuration High-Power LED Driver Author: Keith Curtis Microchip Technology Inc. INTRODUCTION The circuit and firmware described in this application note demonstrates a minimal parts count driver/controller for a high-power (1W or greater) LED. The circuit is based on a buck topology switching power supply using the on-chip comparator peripheral within the PIC12F675 PIC® microcontroller. The switching power supply design ensures efficient power transfer between the system battery a.
