General Description

The PN8368 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.
PN8368 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 PN8368 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 at CS pin. PN8368 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.
