Introduction

This EVM uses a TPS65132S to generate the positive and negative supply voltages needed by LCD
panels in smartphones and tablet PCs. It can also be used as a general-purpose power supply in
applications that need positive and negative supply rails (for example, op-amp or data acquisition circuits).

For easy performance evaluation of the TPS65132S, this EVM has:

Software with a Graphical User Interface (GUI) for reading, writing, exporting, and importing the device
configuration

A USB2ANY interface adapter to control the I

2

C bus

Test points for measuring the most important voltages

Jumpers for enabling and disabling the outputs

Input and output voltage sense terminals for making accurate four-terminal voltage measurements

1.1

Recommended Equipment

In addition to the contents of the EVM box, some or all of the equipment described in the following
subsections is required.

1.1.1

Power Supply

To evaluate the full performance of the TPS65132S, a dc power supply capable of delivering 1.2 A from
2.5 V to 5.5 V is required.

1.1.2

Host Computer

To change the output voltages or configuration of the TPS65132S, a personal computer (PC) with the
following minimum specifications is needed:

Microsoft

®

Windows

®

7 operating system

One free USB port

A minimum of 280MB of free hard disk space (610MB recommended)

A minimum of 512MB of RAM

1.1.3

Software

You can download the latest version of the EVM software from the TI website at

http://www.ti.com/product/tps65132/toolssoftware

(see also

Section 5.2

).

1.2

Applications

The TPS65132S device is suitable for use in any applications that need positive and negative output
voltages in the range ±4 V to ±6 V and output currents less than ±150 mA. Typical applications include:

Smartphone displays

Tablet displays

Split-rail power supply applications
