PN8680M Overview
The PN8680M consists of a Low Standby-Power Primary-Side controller and a 650V avalanche-rugged smart power VDMOSFET, specifically designed for a high performance AC/DC charger or adaptor with minimal external ponents. PN8680M operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. Because of internal HV Start-up circuit, the system with PN8680M can achieve less than 50mW...
