STEVAL-ISA019V3

80 W ESBT quasi-resonant wide-range SMPS demonstration

board based on the L6565 for 3-phase applications

Features

Description

The STEVAL-ISA019V3 demonstration board is a

3-phase auxiliary power supply with an 80 W dual

output SMPS, using the L6565 PWM driver and

the STC04IE170HP ESBT as the main switch.

The combination of these ST parts provides a

high-efficiency solution for high DC input voltage,

a typical requirement of any 3-phase application.

The necessity to handle both high output power

and wide input voltage is resolved using a flyback

stage working in mixed operation mode:

discontinuous and continuous.
