InnoSwitch4-QR Data Sheet
The InnoSwitch4-QR family of off-Line CV/CC Quasi-Resonant (QR) flyback integrated switcher ICs dramatically improve the efficiency of flyback power converters, particularly those requiring a compact form-factor.
The InnoSwitch4-QR family incorporates primary and secondary controllers, a 750 V PowiGaN power switch and safety-rated feedback (FluxLink) into a single IC.
