Description

The STEVAL-ISA118V1 is an offline power

converter in flyback topology with jittered fixed

frequency. The board uses the VIPer16, allowing

the application to handle up to approximately 6 W

over a wide input voltage range, and up to about

10 W in the European single input voltage range.

The VIPer16 can operate with or without an

auxiliary winding; both options are implemented

on the board. When operating with the auxiliary

winding, it can achieve very low standby

consumption. Available protection features

include thermal shutdown with hysteresis,

delayed overload and open-loop failure

protection.
