    Products Detail

    The LC5540LD series are isolated LED drivers that integrate a power MOSFET and control IC. They feature average current and quasi-resonant controls for high power factors and high efficiency with low noise. The ICs include built-in on-time control, startup circuit, soft start, bias assist, leading edge blanking, and maximum on-time limitation. Protections include overcurrent (OCP), overvoltage (OVP), overload (OLP), and thermal shutdown (TSD). These drivers enable compliance with IEC61000-3-2 Class C without input electrolytic capacitors.

    Key Features

    • Built-in On-time Control Circuit, Built-in Startup Circuit, Soft Start Function, Bias Assist Function, Leading Edge Blanking Function, Built-in Maximum On-time Limitation Function, Protections: Overcurrent Protection (OCP): Pulse-by-Pulse, Overvoltage Protection (OVP): Latched Shutdown, Overload Protection (OLP): Latched Shutdown, Thermal Shutdown (TSD): Latched Shutdown
