Chipown PN6795D Supporting CCM Quasi-Resonant Primary-Side Converter General Description The PN6795D 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 adapter with minimal external components. PN6795D operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated, supports DCM and CCM working mode. Because of internal HV Start-up circuit, the system with PN6795D can achieve less than 50mW standby power consumption (230VAC). In CV mode, multi-mode, quasi resonant technique are utilized to achieve high efficiency, provide the additional benefit of reducing EMI, avoid audible noise and make the system meeting Energy star level VI. In CC mode, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin. PN6795D offers complete protections including Cycle-by-Cycle current limiting protection (OCP), over voltage protection (OVP), open loop protection (OLP), over temperature protection (OTP) and CS open or short protection (CSO/SP) etc. AC input over voltage protection (OVP) and brownout protection (BO) are also integrated inside PN6795D, and can be adjusted by system resistor divider.
