1.1 Introduction

The TPS7H2140EVM is the evaluation module (EVM) for the TPS7H2140-SEP and provides a platform to evaluate performance and features. This user's guide provides descriptions for the connectors and test points, the schematic, bill of materials, and board layout of the EVM.

The EVM is designed to be easily configurable for use under different operating conditions or requirements. By default, the EVM is configured as shown in Table 1-1. To change the configuration of the device, please refer to the TPS7H2140-SEP data sheet (SLVSH46) to calculate values of any passive components that need to be changed.
