  • Page 1: Table Of Contents

    The Texas Instruments TPS2553Q1EVM evaluation module (EVM) helps designers evaluate the operation and performance of the TPS2553-Q1. This user’s guide describes the TPS2553Q1EVM evaluation module (EVM). This guide contains the EVM schematic, bill of materials (BoM), assembly drawing, and top and bottom board layouts.

  • Page 2: Introduction

    Introduction The TPS2553Q1EVM is an evaluation module (EVM) for an automotive power-distribution switch with adjustable current-limiting outputs provided by Texas Instruments. The EVM has an operating voltage range of around 2.5 V to 6.5 V, and has four different output current limits, based on jumper placement on the board.
