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.
