    Products Detail

    The LC5540LD series are isolated LED drivers that integrate a power MOSFET and control IC in a DIP8 package. They comply with IEC61000-3-2 Class C harmonics standards without requiring an input electrolytic capacitor. The IC employs average current control for high power factors and quasi-resonant control for high efficiency and low noise. Features include built-in on-time control, startup circuit, soft start, bias assist, leading edge blanking, maximum on-time limitation, and comprehensive protections (OCP, OVP, OLP, TSD).

    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
