Application note
10 W SMPS with HV power MOSFET and the L6565
for three-phase industrial applications

Introduction
This document introduces a solution for industrial power supplies fed by a three-phase
mains. It uses a high voltage power MOSFET with 1500 V breakdown voltage to optimize
the operation of a quasi-resonant flyback converter based on the primary controller L6565.
The STEVAL-ISA034V1 demonstration board has been designed and developed for low
power applications. The board features two is
