The EVLACF01UC65 is a compact 65 W Active Clamp Flyback (ACF) converter designed to evaluate the STACF01A, ACF controller. The board can receive a universal AC input voltage and provides a selectable output voltage based on the USB Power Delivery specifications, from 5 V to 20 V. At the primary side, the STACF01A is paired with MasterGaN1L, a 600 V half-bridge enhancement mode GaN HEMT with high-voltage drivers. The STACF01A integrates a buck boost that allows to achieve low stand-by power consumption with a single transformer’s auxiliary winding. A synchronous rectification based on the SRK1004D is employed at the secondary side to enhance the efficiency. The STACF01A integrates a 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/29526741/evlacf01uc65-65w-compact-board-with-stacf01-controller 2025-11-21 https://elecena.pl/product/29526741/evlacf01uc65-65w-compact-board-with-stacf01-controller 2026-02-04
