The Sanken LC5523F is a power IC for LED drivers, incorporating a power MOSFET and designed for input capacitorless applications to comply with harmonics standards like IEC61000-3-2 class C. It utilizes an average current control method for high power factors and a quasi-resonant topology for high efficiency and low EMI noise.
This IC is intended for isolated designs and features an integrated MOSFET with a minimum Vds rating of 650V and a maximum Rds(on) of 1.9 Ω. It can deliver a maximum output power of 60W on a 230V AC supply and 40W on a universal input supply (85 to 265V AC), based on thermal ratings. The LC5523F includes a rich set of protection features, contributing to low component counts and high performance-to-cost power supplies.
Key features include integrated on-time control, startup, soft-start, bias assist, and Leading Edge Blanking (LEB) circuits. Protection features comprise pulse-by-pulse overcurrent protection (OCP), auto-restart overvoltage protection (OVP), auto-restart overload protection (OLP), and latched shutdown thermal shutdown (TSD).
The LC5523F is housed in a 7-pin TO-220F package and is suitable for mounting through hole. Its operating temperature range is -55°C to 115°C (TA).
