描述 Description

The InnoSwitch?-CE family of ICs dramatically simplify the development

and manufacturing of low-voltage, high current power supplies,

particularly those in compact enclosures or with high efficiency requirements.

The InnoSwitch-CE 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 permit accurate control of both a secondary-side

synchronous rectification MOSFET and optimization of primary-side

MOSFET switching. This improves system reliability, maximizes

efficiency across the power range from full load to low-power standby.
