APPLICATION NOTE 3532
High-Power LED Driver Accepts Wide Input-Voltage Range


Abstract:Circuit based on a buck/boost converter controller regulates current to a white LED, despite an allowed variation of input
voltage from 2.7V to 16.5V.

A similar version of this article appeared as a Design Brief in the January 20, 2005 issue of Electronic Design magazine.

The advent of high-power LEDs capable of replacing incandescent bulbs has produced a need for circuits that efficiently match the
LEDs to available power sources (batteries, car electrical systems, etc.). The circuits should also be able to r……
