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.
