Application note
Universal input voltage power supply for ESBT based
breaker and metering applications

Introduction
This document describes how to design a 3-phase power supply with the UC3845B PWM
driver and the new STC04IE170 ESBT as main switch. It is associated with the release of
the STEVAL-IPB001V1 demo board (see figure below). The design is a complete solution
for the 2 W single output SMPS, which is widely used as a power supply in breaker
applications. However, the design method can also be applied to
