The LC5540LD series is the power IC for the isolated type 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) , even during light load condition.
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.
