Product：PN6367

一、General Description 

The PN6367 consists of a Zero Standby-Power mode Quasi-Resonant (QR) Primary-Side controller and a 720V avalanche-rugged smart power VDMOSFET, specifically designed for a high performance intelligent circuit breaker with minimal external components.PN6367 operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. Because of zero standby
mode, phase current of the system with PN6367 can lower than 0.1mA. In CV mode, the output voltage setting can be adjusted externally by the resistors at FB pin. In CC mode, the current and output power setting can be adjusted externally by the sense resistor
at CS pin. PN6367 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.

1)  Internal 720 V avalanche-rugged smart power VDMOSFET
2)  Zero Standby-Power mode, phase current lower than 0.1mA
3)  Multi-mode and Quasi-Resonant technique achieve high efficiency
4)  ±5% CC Regulation at Universal AC input
5)  Primary-side Sensing and Regulation without TL431 and Opto-coupler
6)  No-need Control Loop Compensation Capacitance
7)  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
