PN8571 - Internal BJT Low Standby-Power QR Primary-side Converter
The PN8571 consists of a Low Standby-Power QuasiResonant(QR) Primary-Side controller and BJT, specifically designed for a high performance AC/DC charger or adapter with minimal external components.
PN8571 operates in primary-side sensing and regulation, so opto-coupler and TL431 could be eliminated.
