STEVAL-ISA031V1

Demonstration board for 40 W auxiliary 3-phase power supply based on the L6565 and STW4N150
  • NRND NRND

This demonstration board introduces a solution for industrial power supplies fed by a 3-phase mains supply. It takes advantage of the high voltage MOSFET (1500 V breakdown voltage) to optimize the operation of the quasi-resonant flyback converter based on the primary controller L6565. The demonstration board has been designed and developed to address low power applications. The board features two outputs, 24 V and 5 V, and is able to deliver more than 40 W. The 5 V output is obtained using an integrated DC-DC converter based on L5970AD, connected on the 24 V output.
