Offline Primary-Side-Regulation (PSR) Quasi-Resonant Valley Switch Controller

FAN1080 is offline Primary−Side−Regulation (PSR) PWM controller with Quasi−Resonant (QR) mode controller to achieved constant−voltage (CV) and constant−current (CC) control for Travel Adaptor (TA) requirement and provide cost−effective, simplified circuit for energy−efficient power supplies.FAN1080 is designed to have good energy efficiency technology that offers options to users to meet different power consumption targets using different startup components.FAN1080 can be used in Travel Adapter design by stand−alone or co−work with secondary−side SR controller FAN6250/FAN6292C. While pairing with FAN6292C, FAN1080 can be used to design a high density Type−C travel adapter in compact system BOM.
