IMX2176F
Off-Line Zero Voltage Switching (ZVS) Flyback Switcher IC with Up to Three CV Outputs or One CV & One CC Output for a Dimmable LED String
Product Details
The InnoMux2-EP IC dramatically improves power conversion efficiency. By independently regulating and protecting each output
the InnoMux-2 family eliminates multiple downstream conversion stages.
InnoMux-2 IC-based designs have low BOM count and small size. The family incorporates both primary and secondary-side controllers, with protection, sense elements and a safety-rated feedback mechanism (FluxLink) into a single IC. The InnoMux-2 IC also includes an LED backlight controller that supports multi-mode dimming making it ideal for monitors, TVs and appliances with lighting or display requirements.
InnoMux2-EP contains enhanced features for maximizing conversion efficiency including quasi-resonant switching in DCM operation, accurate SR control and minimum-threshold-regulation for the LED driver.
