The meaning of the term “high power LED” is rapidly evolving. Although a 350mA LED could easily earn the stamp of “high power” a few years ago, it could not hold a candle to the 20A LED or the 40A laser diodes of today. High power LEDs are now used in DLP projectors, surgical equipment, stage lighting, automotive lighting and other applications traditionally served by high intensity bulbs. The LT3763 is a 60V, synchronous, high current step-down LED driver controller that can be used to drive the latest high power LEDs, with fast PWM dimming response if needed.
