5 V, 0.85 A flyback converter using VIPerô Plus - VIPer01

The STEVAL-ISA177V1 evaluation board implements a wide-range converter in flyback non isolated topology, delivering 0.85 A on a 5 V output for general purpose applications.

The core of the application is the new VIPer01 offline high voltage converter from the VIPerPlus range that intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control.

The main characteristics of the evaluation board are its single layer, small size with minimal BOM, high efficiency and low standby consumption.
