Power Integrations InnoSwitch3 Flyback Switcher ICs

With Integrated High-Voltage Switch, Synchronous Rectification and FluxLink Feedback

The Power Integrations InnoSwitch Family of ICs combines primary, secondary and feedback circuits in a single surface-mounted off-line flyback switcher IC. The InnoSwitch IC incorporates a high-voltage primary-side switch, the primary-side controller, a secondary-side controller for synchronous rectification and an innovative new FluxLink technology that eliminates the need for an optocoupler.


InnoSwitch3-EP Family

Designing and manufacturing of flyback power converters is simplified thanks to the InnoSwitch™3-EP family of ICs. For applications requiring high efficiency and/or compact size such as auxiliary, utility meters, smart grid and industrial power supplies, the InnoSwitch3-EP family combines primary and secondary controllers and safety-rated feedback into a single IC. InnoSwitch3-EP family switcher ICs incorporate multiple protection features with available standard and peak power delivery options, in addition to commonly used auto-restart protection behaviors.

  • Highly Integrated, Compact Footprint 
  • EcoSmart™ Energy Efficiency
  • Advanced Protection & Safety Features
  • Optional Features such as auto-restart output UV protection with option for peak power delivery
  • Full Safety & Regulatory Compliance
  • Eco-Friendly Package (Halogen free and RoHS compliant)

InnoSwitch3-MX

This version of InnoSwitch3 is intended to be used with InnoMux for multiple output, single-stage power supplies for monitors and TVs. This enables very high system efficiency on a small PCB foot print.

The InnoSwitch3-MX dramatically simplifies the development and manufacturing of multiple output power supplies, particularly those in compact enclosures or with high efficiency requirements. The InnoSwitch3-MX architecture is revolutionary in that the devices incorporate both primary and secondary controllers, with sense elements and a safety-rated feedback mechanism into a single IC.

Close component proximity and innovative use of the integrated communication link, FluxLink, permit accurate control of a secondary-side synchronous rectification MOSFET with Quasi-Resonant switching of primary integrated high-voltage switch to maintain high efficiency across the entire load range.
