The is an offline CV/CC fly-back Switcher IC with integrated 650V MOSFET, synchronous rectification and feedback. The IC 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 feed-back 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 10mW no-load in challenging applications such as smart-mobile device chargers.
