Data Sheet(758KB)

The LC5500 series is the power IC for the LED driver which has an incorporated power MOSFET, designed for input capacitorless applications, and making it possible for systems to comply with the harmonics standard (IEC61000-3-2 class C).
The controller adapts the average current control method for realizing high power factors, and the quasi-resonant topology contributes to high efficiency and low EMI noise.
The rich set of protection features helps to realize low component counts, and high performance-to-cost power supply.
