Description

The InnoSwitch?3-MX together with InnoMux dramatically improves

system efficiency by eliminating the boost and buck converter stages.

It also 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 secondaryside

synchronous rectification MOSFET with Quasi-Resonant switching

of primary integrated high-voltage switch to maintain high efficiency

across the entire load range.

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.
