Chipown PN6775H Low Standby-Power Primary-Side Converter General Description The PN6775H consists of a Low Standby-Power Primary-Side controller and a 800V avalanche-rugged smart power VDMOSFET, specifically designed for a high performance AC/DC charger or adapter with minimal external components. PN6775H 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 PN6775H can achieve less than 50mW standby power consumption (230VAC). In CV mode, multi-mode is utilized to achieve high efficiency, avoid audible noise and make the system meeting Energy star level 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. PN6775H 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  Output Features Vo Switch AC/DC Adapter  Battery Charger  Home appliances ±5% 100% ±5% 60% Features Io  Internal 800V avalanche-rugged smart power VDMOSFET  Internal HV Start-up Circuit, Standby power < 50mW  Multi-mode technique  ±5% CC Regulation at Universal AC input VDD SW VDD SW  Primary-side Sensing and Regulation without TL431 and GND SW GND SW Opto-coupler FB SW FB SW  Programmable Cable Drop Compensation CS SW CS SW  No-need Control Loop Compensation Capacitor  Package/Order Information DIP8 Over Temperature Protection (OTP) VDD Under/Over Voltage Protection(UVLO&OVP) Cycle-by-Cycle Current Limiting (OCP) Cs Short/Open Protection (CS O/SP) Open Loop open Protection(OLP) Typical power Order code Package PN6775HSEC-R1 SOP8 6W PN6775HNEC-T1 DIP8 8W Excellent Protection include:      SOP8 85~265 VAC Typical Circuit VDD OTP Block FB GND www.chipown.com DC Output Snubber AC 85~265V CC/CV control Cable comp SUPPLY &UVLO SW HV Startup PWM Switch &Gate Driver CS OCP PN6775H Wuxi Chipown Microelectronics Limited Rev. 1.0 1/12 PDF
