EVAL-LED-ICL8001G-Bulb02 Quasi-Resonant Flyback Converter for Phase Cut Dimming with High Power Factor
The EVAL-LED-ICL8001G-Bulb02 demonstrates the single-stage flyback and PFC controller ICL8001G in an LED Bulb application. Its quasiresonant operation mode, primary side control, integrated PFC and phase-cut dimming control makes it the best in class system solution for dimmable LED bulbs.
EVAL-LED-ICL8001G-Bulb02演示板主要特性：
•High, stable efficiency over wide operating range through quasiresonant operation mode
•Primary side side flyback control with integrated PFC and phase-cut dimming
•Energy efficient phase cut dimming
•Power cell for VCC pre-charging with constant current
•Built-in digital soft-start
•Foldback correction and cycle-by-cycle peak current limitation
•VCC over- and under-voltage lockout
•Auto restart mode for short circuit protection
•Adjustable latch-off mode for output overvoltage protection
•Best in class system BOM for dimmable bulbs
