TPS65912xEVM-081 User's Guide

Abstract

This user’s guide provides a detailed account of the TPS65912x Evaluation Module (EVM) including a

general overview, schematic diagram, board layout, setup instructions, graphical user interface (GUI) and

bill of materials (BOM). Use this EVM for integrated circuit (IC) evaluation and also for design reference.

The TPS65912x is a power management unit (PMU) for processor power.

How to Use This Manual

This document is formatted in order of operation; become familiar with the schematic and layout before

proceeding to the setup section.
