STEVAL-VP22201B

Evaluation board implements a 5V - 1.8W buck converter developed for general purpose applications operating from 85 to 265VAC. The reference design is built around the VIPer222XSTR offline high-voltage converter from the VIPerPlus family with 730V Power MOSFET and PWM current-mode control. The main characteristics of the evaluation board are its small size and minimal BOM, low stand-by consumption and tight line and load regulation over the entire input and output range. Extremely low consumption under no-load condition is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency related losses.
