Description
The InnoSwitch™-EP 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-EP 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 a secondary-side
synchronous rectification MOSFET and optimization of primary-side
switching to maintain high efficiency across the entire load range.
Additionally, the minimal DC bias requirements of the link, enable the
system to achieve less than 10 mW no-load to maximize efficiency in
standby.
