1 General Description
The PN8366 consists of a Low Standby-Power Quasi-Resonant (QR) Primary-Side controller and a avalanche-rugged smart power VDMOSFET(PN8366M 700V,PN8366H 800V), specifically designed for a high performance AC/DC charger or adaptor with minimal external components. PN8366 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 PN8366 can achieve less than 30mW 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. In CC mode, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin. PN8366 offers complete protections including Cycle-by-Cycle current limiting protection (OCP), over voltage protection (OVP), over temperature protection (OTP) and CS open or short protection (CSO/SP) etc.
