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 combination of these ST parts provides a

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.
