Low Standby-Power Primary-Side Converter
General Description
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 components. 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 standby power consumption (230VAC). In CV mode, multi-mode and quasi resonant technique is utilized to achieve high efficiency, avoid audible noise and make the system meeting Energy star class VI. Good load regulation is achieved by the built-in cable drop compensation.
