1 INTRODUCTION
This document presents the information required to operate the TPS65280 PMIC as well as the support
documentation including schematic and bill of materials.
2 BACKGROUND
The TPS65280 PMIC contains a buck converter and two power switches. The buck converter is designed
to provide a 5-V voltage with maximum 4-A continuous currents. The two power switches are designed to
provide current limit at typical 1.2 A while 0.5 A/1 A/2.1 A is available with manufacture trim options.
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 TPS65280. 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.
