Description

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.
