General Description
The pN6780H consists of a Low Standby-Power Primary-Side controller and a 800V avalanche-rugged smart powe!VDMOSFE'T, specifically designed for a high performance AC/DC charger or adapter with minimal external componentsPN6780H operates in primary-side sensing and regulation, so opto-coupler and 'TL431 could be eliminated. Because of internaHV Start+-up circuit, the system with PN6780H can achieve less than 50mW standby power consumption (230VAC). In Cy modemulti-mode is utilized to achieve high efficiency, avoid audible noise and make the system meeting Energy star level Vl. Gioodload regulation is achieved by the built-in cable drop compensation. In CC mode, the curent and output power setting can beadjusted externally by the sense resistor at CS pin. PN6780H offers complete protections including Cycle-by-Cycle currentlim iting protection (0CP), over voltage protection (OV), over temperature protection (OTP) and CS open or short protection (CsO/SP)etc.
