1 Introduction

This document presents the information required to operate the TPS5402 as well as the support documentation including schematic and bill of materials.

2 Background

The TPS5402 is designed to provide 1.7-A continuous current with an operational range of 4.5 V to 28 V and an external set switching frequency ranging from 50 kHz to 1.1 MHz.

As there are many possible options to set the converters, Table 2-1 presents the performance specification summary for the EVM.

Table 2-1 Summary of Performance

TEST CONDITIONS	PERFORMANCE
V_IN = 3.5 V to 28 V f_SW = 300 kHz (25°C ambient)	Buck: 3.3 V, up to 1.7 A

The evaluation module is designed to provide access to the features of the TPS5402. Some modifications can be made to this module to test performance at different input and output voltages, current and switching frequency. Please contact TI Field Applications Group for advice on these matters.
