Description
This demonstration board introduces a solution for industrial power supplies. It takes advantage of the high voltage Power MOSFET, i.e. 1500 V breakdown voltage, to optimize the operation of the flyback converter based on the primary controller UC3844B. The demonstration board has been designed and developed in order to address medium power applications. The board features two outputs, 24 V, 5V or 3.3 V, and is able to deliver more than 100 W in total. The 5 V/3.3 V output is obtained by means of an integrated DC-DC converter based on L5970D, connected to the 24 V output, and adjustable by means of an external voltage divider. STEVAL-ISA054V1
