STMicroelectronics STEVAL-VP12201F Converter Evaluation Board

STMicroelectronics STEVAL-VP12201F Converter Evaluation Board implements a 12V – 5W isolated flyback converter developed for general purpose applications supplied from 85 to 265V_AC. The reference design is built around the new VIPer122LS offline high-voltage converter from the VIPerPlus family, with embedded 730V Power MOSFET and PWM current-mode control.

The main characteristics of the STMicroelectronics STEVAL-VP12201F are its small size and minimal BOM, high efficiency, low standby consumption, and tight line and load regulation over the entire input and output range. Extremely low consumption under no-load conditions is ensured thanks to the burst-mode operation, which reduces the average switching frequency and minimizes all frequency-related losses.

VIPer122LS operates at a fixed frequency 60kHz with frequency jittering to meet the standards regarding an electromagnetic disturbance.
