PSU and Converter Solution Eval Boards

STMicroelectronics provides turnkey solutions that address the growing demand for innovation to reach higher efficiency, higher power density and lower standby power designs. This is achieved through a wide range of power discrete components, analog ICs and digital processors. Explore the range of evaluation boards below to find the perfect fit for your design needs.

Two new quasi-resonant fly-back SMPS designs

The STEVAL-ISA171V1 (12 V /15 W, based on the ViPer35HD) and the STEVAL-ISA162V1 (12 V / 10 W, based on the ViPer25HD) evaluation boards, implement a wide-range AC input voltage, isolated fly-back SMPS (switched mode power supply) operated in quasi-resonant mode to deliver high efficiency (>82% in active mode). They also feature low consumption under no-load conditions thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency-related losses.
