STMicroelectronics STACF01A/MasterGaN1L | Demoboard EVLACF01UC65
65W compact board with STACF01 controller
Overview
| Topology | Flyback Converter |
| Input voltage | 90-264 V |
| Output 1 | 20 V / 3.25 A |
| IC revision | 1 |
Description
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.
Features
Universal AC input voltage: 90~264 VAC, 47~63 HzMaximum output power: 65 WSelectable output voltage: 5-9-15-20 VDCPeak efficiency:93% full load @90VACStand-by power consumption:60 mW@115V AC, 5 Vout68 mW@230 VAC, , 5 VoutCompact design: 60 x 35 x 22 mm (L,W,H). Power density: 23W/in3
