The EVLSTACF01-65WU is a 65 W Active Clamp Flyback (ACF) converter designed to evaluate the STACF01, ACF controller. The board can receive a universal AC input voltage and provides a selectable output voltage based on the USB PD specifications, from 5 V to 20 V. At the primary side, the STACF01 is paired with the MasterGaN1L, a 600 V half-bridge enhancement mode GaN HEMT with high-voltage drivers. The STACF01 integrates a buck boost that allows to achieve low standby power consumption with a single transformer’s auxiliary winding. A synchronous rectification based on the SRK1004 is employed at the secondary side to enhance the efficiency. The STACF01 integrates an 800 V rated high-voltage startup, and offers a full set of protections and features, such as AC-brownout, X-CAP discharge, overload and short-circuit protection, output overvoltage protection. https://elecena.pl/product/27586567/evlstacf01-65wu-usb-pd-board-with-stacf01-controller 2024-12-30 https://elecena.pl/product/27586567/evlstacf01-65wu-usb-pd-board-with-stacf01-controller 2025-06-29
