1 Introduction

This document describes the STEVAL-ISA010V1 demonstration board, which is designed
as an example of a simple non-isolated auxiliary power supply for a range of input voltages
from 85 VAC to 500 VAC.
There is an ever-increasing demand for small power supplies capable of working without
voltage range limitations, even at nominal levels of 400 VAC and 415 VAC, respectively. The
real voltage levels can reach 500 VAC (415 V + 20%). The major market
