Description

The STEVAL-ISA081V1 demonstration board is a

switched mode power supply (SMPS)

demonstration board and it is an isolated SMPS

capable of delivering a 12 W output over a wide

input voltage range.

It is designed for a mains application focusing on

cost and size effective solutions.

The STEVAL-ISA081V1 SMPS generates 12 V

nominal output voltage using primary regulation

and it is based on the VIPER26 monolithic

converter, integrating a high voltage MOSFET

and PWM controller in one package.
