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.
The InnoMux family includes the industry's first power devices to feature a 1700 V GaN switch. The high voltage rating achieved by PowiGaN™ technology marks a watershed moment in the advancement of GaN power electronics, making it possible for GaN devices to replace costly silicon carbide (SiC) transistors in applications such as automotive chargers, solar inverters, three-phase meters and other industrial power systems.
