The InnoSwitch™3-CE family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-CE family incorporates primary and secondary controllers and safety-ratedfeedback into a single IC.InnoSwitch3-CE family devices incorporate multiple protection features including line over and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown. Devices are available that support the common combinations of latching and auto-restart behaviors required by applications such as chargers, adapters, consumer electronics and industrial systems. The devices are available with and without cable-drop compensation.


  • Lowest cost and component count for a network power supply
  • Output voltage regulation, ±5%
  • Reduced dissipation during output short circuit fault
  • <30 mW no-load input power
  • Average efficiency at PCB >91%, and >88% at the end cable (1.8 m, #22 AWG)
  • 6% cable drop compensation
