1 INTRODUCTION
This document presents the information required to operate the TPS5405 as well as the support
documentation including schematic and bill of materials.
2 BACKGROUND
The TPS5405 is designed to provide fixed 5-V output and 1.5-A continuous current with an operational
range of 6.5 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 1 presents the performance specification
summary for the EVM.

The evaluation module is designed to provide access to the features of the TPS5405. 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.
