STEVAL-ISA031V1: 40 W SMPS with HV MOSFET and L6565
for three-phase industrial applications
Introduction
This document introduces a solution for industrial power supplies fed by a three-phase
mains. It employs a high voltage (1500 V breakdown voltage) power MOSFET to optimize
the operation of a quasi-resonant flyback converter based on the primary controller L6565.
The demonstration board has been designed and developed specifically for low power
applications. The board features two outputs, 24 V and 5 V, and is capable of delivering
more than 40 W of output power. The 5 V output is obtained by means of an integrated DC-
DC converter based on the L5970AD 1.5 A switch step-down switching regulator, connected
to the 24 V output. The demonstration board is available through order code STEVAL-
ISA031V1.
