InnoSwitch™-CH Family of ICs

Power Integrations' InnoSwitch™-CH family of ICs combines primary, secondary, and feedback circuits in a single surface-mounted off-line flyback switcher IC. The InnoSwitch-CH IC incorporates the primary FET, the primary-side controller, and a secondary-side synchronous rectification controller. The new IC also includes an innovative new technology, FluxLink™, which safely bridges the isolation barrier and eliminates the need for an optocoupler. The incorporation of the secondary-side controller enables a shoot-through proof synchronous rectification FET drive while delivering fast transient response, exceeding all world-wide efficiency standards, including the Code of Conduct Version 5 and DoE Version 6 regulations.
