FEATURES AND BENEFITS
DESCRIPTION
● Integrated on-time control circuit (it realizes high power The LC5500 series is the power IC for the LED driver factor by average current control) which has an incorporated power MOSFET, designed for● Integrated startup circuit (no external startup input capacitorless applications, and making it possible for circuit necessary) systems to comply with the harmonics standard (IEC61000-
● 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)
● Integrated Leading Edge Blanking (LEB) circuit 3-2 class C). The controller adapts the average current control method for realizing high power factors, and the s quasi-resonant topology contributes to high efficiency and n low EMI noise. ig The rich set of protection features helps to realize low coms ponent counts, and high performance-to-cost power supply.
