Off-Line CV/CC Flyback Switcher IC 12-Pin eSOP

The InnoSwitch™-CH family of ICs dramatically simplifies the development and manufacturing of low-voltage, high current power supplies, particularly those in compact enclosures or with high efficiency requirements. The InnoSwitch-CH 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 enables the system to achieve less than 10 mW no-load in challenging applications such as smart-mobile device chargers.
