PN8386 Chipown Low Standby-Power Quasi-Resonant Primary-Side Converter General Description The PN8386 consists of a Low Standby-Power Quasi-Resonant (QR) 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. PN8386 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 PN8386 can achieve less than 50mW standby power consumption (264VAC). 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.
