Product Description

Datasheet
 

General Description
The PN6370P consists of a Low Standby-Power Quasi-Resonant (QR) Primary-Side controller and a 690V avalanche-rugged smart power VDMOSFET, specifically designed for a high performance AC/DC charger or adaptor with minimal external components. PN6370P 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 PN6370P can achieve less than 30mW 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. PN6370P 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. AC input over voltage protection (OVP) and brownout protection (BO) are also integrated inside PN6370P, and can be adjusted by system resistor divider.
