World’s First Fully Integrated
Active Clamp Flyback Controllers
High efficiency is key to achieving power density without overheating the adapter’s case. The SZ1101 and SZ1105 deliver over 93% efficiency at full rated output power with an all silicon design; while using an industry standard silicon MOSFET main switch. Keeping it cool to the touch and maintaining the small size consumers have come to expect.
Both devices reduce bill-of-material cost not only by integrating the ACF circuit, but also by enabling designers to use a lower cost transformer, SR FET, clamp capacitor and input filter compared to conventional ACF or flyback-controller-based designs.
