STEVAL-ISA023V2: 24W, -5V @ 3A, -12V @ 800mA, 90 ~ 265VAC

Summary

This document describes the reference design of the 25W Switch Mode Power Supply which is dedicated to industrial or white goods applications. The board accepts wide range input voltages (90 to 265Vrms) and delivers 2 output voltages.

The Switch mode power supply is based on the VIPer53E. The VIPer53E combines in the same package an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet. High efficiency and low standby consumption are the main characteristics of this board. Such features, coupled with minimal part requirements and global low cost in addition to, makes it an ideal solution for powering industrial or consumer equipment, meeting worldwide standards.
