Applications

• Chargers and adapters for smart mobile devices

• High efficiency, low voltage, high current power supplies

Description

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.
