STEVAL-ISA162V1: 10W, 12V @ 0.84A, 90 ~ 265 VAC

Summary

The STEVAL-ISA162V1 evaluation board implements an isolated flyback (12 V/0.84 A) 10 W wide-range mains developed for general purpose applications. The core of the application is the VIPer25HD, a new off-line high voltage converter from the VIPerPlus family. The device is a high-voltage converter that "smartly" integrates an 800 V rugged power MOSFET with PWM current mode control.

The main characteristics of the board are its small size, minimal BOM, high efficiency and low standby consumption. Extremely low consumption under no-load conditions is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency related losses. The VIPer25HD operates in quasi-resonant mode, a feature that helps it meet standards for electromagnetic disturbance. The IC features high level protection including duallevel OCP, output overvoltage, short-circuit and thermal shutdown with hysteresis. After the removal of a fault condition, the IC automatically restarts.
