STEVAL-ISA019V1
Description
This evaluation board is a 3-phase auxiliary power
supply with an 80 W dual output SMPS, using the
L6565 PWM driver and the STC04IE170HV ESBT
as the main switch. The combination of these ST
devices provides a high-efficiency solution for high
DC input voltage, a typical requirement for any
three-phase application. The necessity to handle
both high output power and wide input voltage is
satisfied using a flyback stage working in mixed
operation mode: discontinuous and continuous.
