1.1 Introduction

The LM5185-Q1 single-isolated-output (SIO) evaluational module (EVM), otherwise known as LM5185EVM-SIO, is designed to demonstrate the features and functionality of the LM5185-Q1 device. The device is a 100-VIN Primary-Side-Regulated (PSR) flyback DC/DC controller based on sampling the primary winding voltage of the transformer to achieve tight output regulation and high efficiency, without using the opto coupler nor tertiary bias winding like in a conventional flyback converter.

This user's guide describes the characteristics and operation of the evaluataion module LM5185EVM-SIO. This document provides examples and instructions on how to use the evaluation module, and presents typical performance curves and key waveforms. Throughout this document, the terms of evaluation board, evaluation module, and EVM are synonymous with the LM5185EVM-SIO. This document also includes a schematic, reference printed circuit board (PCB) layout, and a complete bill of materials (BOM).
