STEVAL-ISA081V1 demonstration board based on a 12 V / 1 A
isolated flyback
Introduction
The purpose of this document is to provide information on the STEVAL-ISA081V1 switched
mode power supply (SMPS) demonstration board. The STEVAL-ISA081V1 is an isolated
SMPS capable of delivering a 12 W output over a wide input voltage range. It is designed for
a mains application focused on providing a cost-effective and space saving solution.
The STEVAL-ISA081V1 SMPS generates 12 V nominal output voltage using primary
regulation. This board is based on VIPer™26LD - a monolithic converter integrating a high
voltage MOSFET and PWM controller in one package.
This document contains a fundamental technical description of the demonstration board
(schematic diagram, PCB details, and bill of materials) as well as basic measurements
(load regulation, efficiency, standby behavior, EMI and thermal behavior data).
The last section of this document contains short recommendations on how to set different
output voltages in the range of 10 to 18 V and how to improve efficiency up to 86%.
