Introduction

To operate this EVM properly, the user must connect and properly configure the following components.

A computer with a USB port is required to operate this EVM. The TPS62351 interface software runs on

the PC and communicates with the EVM via the PC’s USB port. The user can send commands to the

internal registers of the TPS62351 through the USB port.

• Windows2000™ or WindowsXP™ operating System

• USB port

• Minimum of 30 MB of free hard disk space (100 MB recommended)

• Minimum of 256 MB of RAM

The TPS62351EVM-122 PCB contains the TPS62351 IC and its required external components. This

board contains several jumpers and connectors that enable the user to customize the board for

specific operating conditions.

The USB Interface Adapter is the link that allows the PC and the EVM to communicate. One end of the

USB Interface Adapter connects to the PC with the supplied USB cable; the other side of the USB

Interface Adapter connects to the EVM with the supplied ribbon cable.

When writing a command to the EVM, the interface program running on the PC sends the commands

to the PC USB port. The USB Interface Adapter receives the USB command, converts the signal to an

C™ protocol, and sends the I

C™ signal to the TPS62351 EVM board.

Texas Instruments has provided software to assist the user in evaluating this EVM. The software can

be installed from the supplied CD or downloaded from the web at www.ti.com .

This section describes the jumpers and connectors on the EVM as well as how to properly connect, setup,

and use the TPS62351EVM-122.

This is the positive input supply voltage to converter 1. The leads to the input supply should be twisted

and kept as short as possible to minimize EMI transmission.

This is the return connection for the input power supply of converter 1.

This connector is the I

C™ input for converter 1.
