This is a data brief about STMicroelectronics' demonstration board for a 40W auxiliary 3-phase power supply based on the L6565 and STW4N150. It features an input voltage range of 185V to 460V, input frequency range of 50/60Hz, output voltage of 24V @ 1.7A and 5V @ 1A, and a total output power of 40W. The board utilizes a high voltage MOSFET (1500V breakdown voltage) to optimize the operation of the quasi-resonant flyback converter based on the primary controller L6565. It is designed for low power applications and has two outputs, 24V and 5V, capable of delivering more than 40W.
