Overview

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): pulse-by-pulse ▫ Overvoltage protection (OVP): latched shutdown ▫ Overload protection (OLP): latched shutdown ▫ Thermal shutdown (TSD): latched shutdown Package: 8-pin DIP Description LC5550LD series are PWM and quasi-resonant topology non-isolated buck LED driver ICs.
They incorporate separate controller an...
