1 Introduction

The TPS65217 device is a highly integrated power management solution for portable electronics. Features of the TPS65217 include:

• Power path management for Lithium-ion battery, USB, and AC inputs

• Linear battery charger

• 3DC/DCstep-down (buck) converters

• 2LDOs

• 2load switches (also configurable as LDOs)

• White LED driver capable of driving up to 20 LEDs

2 Requirements

2.1 Software

The EVM will power-up and operate without the use of software (refer to Note in Section 2.3). However, to execute I2C read and write commands to examine status bits or change voltage outputs, the required software (refer to Section 8) must be installed.

2.2 Host Computer

A computer with an available USB port is required to make use of the EVM software. The EVM software runs on the computer and communicates with the EVM through the USB2ANY interface adapter hardware.

2.3 Power Supply

A DC power supply capable of delivering up to 5V and 3A is required to operate this EVM.

2.4 Evaluation Module PCB

Figure 1 shows the TPS65217CEVM printed circuit board (PCB). The TPS65217AEVM, TPS65217BEVM, and TPS65217DEVM used the same PCB with a different IC revision installed. Unless otherwise noted, TPS65217xEVM refers to all four EVM assembly options.

5 Software

Software support for controlling the TPS65217 over I2C using the USB2ANY adapter can be downloaded from www.ti.com/tool/IPG-UI. To install the software and learn how to use the IPG-UI GUI, follow the instructions in the IPG-UI User’s Guide .
