InnoMux2-BL Off-Line ZVS Flyback Switcher ICs

Power Integrations InnoMux™2-BL Off-Line Zero Voltage Switching (ZVS) Flyback Switcher ICs offer one constant voltage (CV) and up to four constant current (CC) outputs for dimmable LED strings in monitors or display panels. These modules provide accurate, isolated, off-line CV and CC regulation using a single transformer, which reduces the power sub-system component count and board area. The multiple-output, single-stage architecture eliminates DC/DC post regulators, providing regulated outputs. The InnoMux2-BL series incorporates both primary and secondary-side controllers with sense elements, protection, and a safety-rated FluxLink™ feedback mechanism into a single IC. Power Integrations InnoMux2-BL Off-Line ZVS Flyback Switcher ICs integrate enhanced features for maximizing conversion efficiency, including accurate SR control, quasi-resonant switching in discontinuous conduction mode (DCM) operation, and minimum threshold regulation for LED drivers.
