AP33510 Quasi-Resonant Flyback GAN Controller

Diodes Incorporated AP33510 Quasi-Resonant Flyback GAN Controller is specially designed for offline flyback power supplies that require low standby power, high-power density, and comprehensive protection. The device operates in QR mode at full load allowing switching events to occur in the drain-source valley, minimizing switching loss. The AP33510 has an internally limited switching frequency of 150kHz maximum. The device ensures stable valley switching and prevents transformer audible noise caused by frequency hopping via a proprietary valley-lockout technique inside.
