    Products Detail

    The LYTSwitch-1 family is a single-stage LED driver IC designed for high power factor and constant current output in non-isolated buck topology. It integrates a high-voltage 725 V MOSFET with a variable on-time Critical Conduction Mode controller, providing high efficiency (>93%), low EMI, and excellent line noise rejection. The devices support wide input voltage range (90 VAC – 308 VAC) and are optimized for LED bulbs and tubes with comprehensive protection features including input/output overvoltage protection, thermal foldback, and auto-restart.

    Key Features

    • Single-stage PFC and CC output
    • Power factor >0.9
    • High efficiency >93%
    • Robust 725 V MOSFET
    • Critical Conduction Mode (CrM) buck
