LC5523D Product details

Description

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 (IEC610003-2 class C).

Features

Integrated on-time control circuit (it realizes high power factor by average current control).
Integrated startup circuit (no external startup circuit necessary).
Integrated soft-start circuit (reduces power stress during start-up on the incorporated power MOSFET and output rectifier).
Integrated bias assist circuit (improves startup performance, suppresses VCC voltage droop during operation, and allows use of low-rated ceramic capacitor on VCC pin).
