* Integrated soft-start circuit (reduces power stress during start-up on the incorporated power MOSFET and output rectifier)

* Integrated

LC5550LD General Description

LC5550LD series are PWM and quasi-resonant topology non-isolated buck LED driver ICs. They incorporate separate controller and power MOSFET chips, and are designed for input capacitorless applications. The controller adapts the average current control method for realizing high power factors. The ric.
