InnoSwitch-CP

Off-Line CV/CC Flyback Switcher IC with Integrated 650 V MOSFET

This is an active product with a newer version available.
Suggested Alternative: InnoSwitch3-CP
Applications

Product Details

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 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.
