EVLACF01UC65

EVLACF01UC65 is a STACF01 non-complementary active clamp flyback controller demonstration board. It 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 5V to 20V. The STACF01A integrates a buck-boost that allows for low stand-by power consumption with a single transformer’s auxiliary winding. The STACF01A integrates a 800V 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, and output overvoltage protection. Applications include AC-DC adapters for smartphones, laptops, and other handheld devices, and offline SMPS.
