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.
