Using the TPS2560EVM-424 and TPS2561EVM-424

This user’s guide describes the TPS2560EVM-424 and TPS2561EVM-424 evaluation modules (EVM).

This guide contains the EVM schematic, list of materials, assembly drawing, and top and bottom board

layouts.

1 Introduction

The TPS2506EVM-424 and TPS2561EVM-424 are evaluation modules (EVM) for Texas Instruments’

power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range.

An on-board jumper sets the output current-limit to either 0.5 A or 1 A. The board is designed for the 5-A

capability of the TPS2560 or TPS25561. Test points provide convenient access to all critical node

voltages.

2 Description

The PCB top-side accepts a power-distribution switch in a SON-10 (DRC) package with a thermal pad.

These switches have dual enable, outputs and over-current status outputs. They have a single

over-temperature shutdown and operate in current limit mode only. Outputs may be connected in parallel

for twice the current output.

TPS2560 is enabled active LO while TPS2561 is enabled active HI.
