Chipown PN6775 Low Standby-Power Primary-Side Converter General Description The PN6775 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. PN6775 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 PN6775 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. In CC mode, the current and output power setting can be adjusted externally by the sense resistor at CS pin. PN6775 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 (CS O/SP) etc. Applications ■ Switch AC/DC Adaptor ■ Battery Charger Output Features Features ■ Internal 650V avalanche-rugged smart power VDMOSFET ■ Internal HV Start-up Circuit, Standby power < 50mW ■ Multi-mode technique ■ ±5% CC Regulation at Universal AC input ■ Package/Order Information Primary-side Sensing and Regulation without TL431 and Opto-coupler ■ Programmable Cable Drop Compensation ■ No-need Control Loop Compensation Capacitance ■ Excellent Protection Coverage:      Over Temperature Protection (OTP) VDD Under/Over Voltage Protection(UVLO&OVP) Cycle-by-Cycle Current Limiting (OCP) Cs Short/Open Protection (CS O/SP) Feedback Loop open Protection(OLP) Order code Package PN6775SEC-R1 SOP8 Typical power 85~265 VAC 6W Typical Circuit V DD OTP Block FB GND www.chipown.com.cn DC O utput Snubber AC 85~265V CC/CV control Cable com p SUPPLY &U V LO SW HV Startup PW M Sw itch &G ate D river O CP CS PN 6775 © 2019 Wuxi Chipown Microelectronics Limited Rev.1907 July.-2019 1 / 12 PDF
