Datasheet Summary
LC5550LD Series
Single-Stage Power Factor Corrected High Efficiency Non-Isolated Buck LED Driver
Features and Benefits
- PWM and quasi-resonant topology
- Integrated on-time control circuit (it realizes high power factor by average current control)
- 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
- Integrated maximum on-time limit circuit
- Protection Features
: ▫ Overcurrent protection (OCP):...
