PN8571P - Internal BJT Low Standby-Power Primary-side Converter

Datasheet Summary

Description

The PN8571P consists of a Low Standby-Power PrimarySide controller and BJT, specifically designed for a high performance AC/DC charger or adaptor with minimal external components.

PN8571P operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated.

PN8571P Chipown Internal BJT Low Standby-Power Primary-side Converter General description The PN8571P consists of a Low Standby-Power PrimarySide controller and BJT, specifically designed for a high performance AC/DC charger or adaptor with minimal external components. PN8571P operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated. In CV mode, multi-mode technique 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.
