    Products Detail

    The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability. The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor. The advanced primary-side control provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits. It incorporates a 725 V power FET, continuous-mode PWM controller, frequency jittering, and protection circuitry including cycle-by-cycle current limit and hysteretic thermal shutdown.

    Key Features

    • Single-stage combination of power factor correction and accurate constant-current output
    • Enables very long lifetime designs (no electrolytic capacitors)
    • Eliminates optocoupler and all secondary current control circuitry
    • Eliminates control loop compensation circuitry
    • Simple primary-side PWM dimming interface
    • Universal input voltage range
    • LNK403-410 optimized for flicker-free TRIAC dimming
    • EcoSmart™ – Energy Efficient: >90% achievable efficiency, reduces component count, no current sense resistors, low standby power
    • Advanced Protection and Safety Features: Auto-restart for short-circuit protection, open circuit fault detection, thermal shutdown, high voltage creepage
    • Green Package: Halogen free and ROHS compliant

    Application scenarios

    • Off-line LED driver
