The InnoSwitch3-EP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-EP family combines primary and secondary controllers and safety-rated feedback into a single IC. InnoSwitch3-EP family devices incorporate multiple protection features including line over and undervoltage protection, output overvoltage and over-current limiting, and over-temperature shutdown.
Compact Footprint Up to 94% efficiency across full load range Exceptional CV/CC accuracy, independent of external components Adjustable accurate output current sense using external output sense resistor Less than 15 mW no-load including line sense Easily meets all global energy efficiency regulations Low heat dissipation Advanced Protection / Safety Features Secondary MOSFET or diode short-circuit protection Open SR FET-gate detection Fast input line UV/OV protection
