Description
The InnoSwitch™-CP 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-CP 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 entire load range and achieves no-load consumption
of less than 10 mW.
