Chipown PN8390 Supporting CCM Quasi-Resonant Primary-Side Converter General Description Features The PN8390 consists of a Low Standby-Power QuasiResonant (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.  Internal 650 V avalanche-rugged smart power VDMOSFET Internal HV Start-up Circuit, t, Standby power consumption < 50mW at 230VAC Support CCM and DCM working mode Multi-mode and Quasi-Resonant technique achieve high efficiency, meeting energy star class VI Using Slope Compensation Technology, No Second Harmonic Oscillation ±5% CC Regulation at Universal AC input Primaryside Sensing and Regulation without TL431 and Opto-coupler Programmable Cable Drop Compensation No-need Control Loop Compensation Capacitance, No Diode Noise Excellent Protection Coverage:  Over Temperature Protection (OTP)  VDD Under/Over Voltage Protection(UVLO&OVP)  Cycle-by-Cycle Current Limiting (OCP)  CS Open or Short Protection  Feedback Loop Open Protection (OLP)  AC Brownout Protection    PN8390 operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated, support CCM and DCM working mode. Because of internal HV Start-up circuit, the system with PN8390 can achieve less than 50mW standby power consumption (230VAC). In CV mode, multimode and quasi resonant technique is utilized to achieve high efficiency, avoid audible noise and make the system meeting Energy star class VI. Excellent EMI performance is achieved with frequency modulation. In CC mode, the current and output power setting can be adjusted externally by the sense resistor at CS pin.     PN8390 offers complete protections including Cycle-byCycle current limiting protection (OCP), over voltage protection (OVP), 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 PN8390, and can be adjusted by system resistor divider.  Applications   Switch AC/DC Adaptor Set-TOP Box Power etc. Package/Order Information Output Features Vo SOP8 ±5% DIP8 CS SW CS SW FB SW FB SW 100% 60% ±5% Io GND SW GND SW VDD SW VDD SW Order code Package PN8390SE-M1 PN8390NE-M1 PN8390SE-P1 PN8390NE-P1 SOP8 DIP8 SOP8 DIP8 Typical power 90~265VAC 18W 24W 18W 24W Typical Application D Snubber AC 90~265V VDD OTP Block FB CC/CV control SUPPLY &UVLO DC Output SW HV Startup ICS ID PWM Switch &Gate Driver VSW GND www.chipown.com Cable comp CCM waveform CS OCP Slope PN8390 Wuxi Chipown Microelectronics Limited Rev. 1.1 1/12 PDF
