InnoMux2-EP Off-Line ZVS Flyback Switcher ICs

Power Integrations InnoMux™2-EP Off-Line Zero Voltage Switching (ZVS) Flyback Switcher ICs feature up to three constant voltage (CV) outputs or one CV and one constant current (CC) output for dimmable LED strings in monitors, TVs, and appliances with lighting or display requirements. The InnoMux2-EP modules are designed to greatly improve power conversion efficiency. By independently regulating and protecting each output, the ICs eliminate multiple downstream conversion stages. Power Integrations InnoMux2-EP Off-Line ZVS Flyback Switcher ICs incorporate both primary and secondary-side controllers, with protection, sense elements, and a safety-rated FluxLink™ feedback mechanism into a single IC. The modules include enhanced features for maximizing conversion efficiency, including quasi-resonant switching in discontinuous conduction mode (DCM) operation, accurate SR control, and minimum threshold regulation for LED drivers.
