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.
