EVLSTACF01-65WU USB-PD Demonstration Board STACF01

STMicroelectronics EVLSTACF01-65WU USB-PD Demonstration Board STACF01 is a 65W Active Clamp Flyback (ACF) converter designed to evaluate the STACF01 ACF controller. The STMicroelectronics EVLSTACF01-65WU board can receive a universal AC input voltage and provides a selectable output voltage based on the USB PD specifications, from 5V to 20V. On the primary side, the STACF01 is paired with the MasterGaN1L, a 600V half-bridge enhancement-mode GaN HEMT with high-voltage drivers. The STACF01 integrates a buck boost that allows the device to achieve low standby power consumption with a single transformer’s auxiliary winding. The STACF01 also integrates an 800V-rated high-voltage startup and offers a full set of protections and features, such as AC brownout, X-CAP discharge, overload/short-circuit protection, and output overvoltage protection. Synchronous rectification based on the SRK1004 is employed on the secondary side to enhance efficiency.
