Description
The STEVAL-ISA030V1 evaluation board is a
complete solution for a 5 W single output SMPS,
the type widely used as a power supply in
metering applications. The design is based
primarily on ST’s L6565 PWM driver and the
STC04IE170HP as the main switch. The design
method can also be applied to an SMPS designed
for other applications which work on a threephase mains, and can easily be upgraded for
higher output power.
