STEVAL-ISA034V1

10 W 3-phase auxiliary power supply

based on the L6565 and STW3N150

Features

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

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.
