Products Detail

The LC5540LF series is a single-stage power factor corrected off-line switching regulator IC with integrated power MOSFET. It uses average current control for high power factor and quasi-resonant topology for high efficiency and low EMI. The series includes integrated startup, soft-start, bias assist, leading edge blanking, and maximum on-time limit circuits. Protection features include overcurrent, overvoltage, overload, and thermal shutdown. Housed in 7-pin TO-220F packages, it enables compact designs with low component count for LED lighting applications.

Key Features

Integrated on-time control circuit for high power factor
Integrated startup circuit (no external startup needed)
Integrated soft-start circuit (reduces power stress)
Integrated bias assist circuit (improves startup, suppresses VCC droop)
Integrated Leading Edge Blanking (LEB) circuit
Integrated maximum on-time limit circuit
Protection features: OCP (pulse-by-pulse), OVP (latched shutdown), OLP (latched shutdown), TSD (latched shutdown)
Quasi-resonant topology for high efficiency and low EMI
Incorporated power MOSFET with V_DSS(min) from 650V to 800V

Application scenarios

LED lighting fixtures
LED light bulbs
