STEVAL-ISA096V1 -12 V/150 mA adaptable buck-boost converter

Introduction

The purpose of this document is to describe the STEVAL-ISA096V1 switched mode power

supply (SMPS) demonstration board. The STEVAL-ISA096V1 is a non-isolated SMPS

designed in buck-boost topology capable of delivering up to 2 W output over a wide input

voltage range, providing a cost-effective and space-saving solution.

It also offers the user the possibility of adapting the circuit to their needs thanks to the

availability of a free PCB area.

The STEVAL-ISA096V1 SMPS generates a 12 V nominal output voltage. This board is

based on VIPer™06XS - a monolithic converter integrating an 800 V avalanche rugged

MOSFET and PWM controller in one package.

This document contains a basic technical description of the demonstration board (schematic

diagram, PCB details, and bill of material) as well as the most significant parameter

measurements (load regulation, efficiency, standby behavior, EMI and thermal behavior

data).
