Description
This evaluation board offers a solution for
industrial power supplies fed by 3-phase mains. It
takes advantage of the high voltage MOSFET
STW3N150 to optimize the operation of the quasi-
resonant flyback converter based on the primary
controller L6565. The STW3N150 is a 1500 V
power MOSFET, designed with
STMicroelectronics’ proprietary high voltage
"MESH OVERLAY™" technology. Thanks to this
technology, the switch features very low R_DS(on)
per area, low gate charge and high switching
performance. The evaluation board has been
designed and developed to address low power
applications. It features two isolated outputs (12 V
and 5 V) and is capable of delivering up to 10 W
of output power.
