LC5566LD

Package Image

Package:DIP8 (Pin 7 Removed)

The LC5560LD series is the power IC for the non-isolated type LED driver which has an incorporated powerMOSFET, 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.
