TPS62350EVM-201 Evaluation Module
1 Introduction
1.1 Requirements
To operate this EVM properly, connect and properly configure the following components:
A personal computer (PC) with a USB port is required to operate this EVM. The TPS62350 interface
software runs on the PC and communicates with the EVM via the PC’s USB port. Commands can be
sent to the internal registers of the TPS62350 through the USB port.
Personal Computer Requirements
• Microsoft
®
Windows
®
2000 or Windows XP operating system
• USB port
• Minimum of 30 MB of free hard disk space (100 MB recommended)
• Minimum of 256 MB of RAM
Printed-Circuit Board Assembly
The TPS62350EVM-201 PCB contains the TPS62350 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.
USB Interface Adapter
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 a command is written 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 I
2
C protocol, and sends the I
2
C signal to the TPS62350 EVM board
Software
Texas Instruments provides software to assist in evaluating this EVM. The software can be installed
from the supplied CD or downloaded from the Texas Instruments Web site at
www.ti.com .
2 Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the TPS62350EVM-201.
2.1 Input/Output Connector Descriptions
2.1.1 J1 – VIN
This is the positive input supply voltage to the converter. The leads to the input supply should be twisted
and kept as short as possible to minimize EMI transmission.
2.1.2 J2 – GND
This is the return connection for the input power supply of the converter.
2.1.3 J3 – I
2
C Input
This connector is the I
2
C input for the converter.
2.1.4 J4 – SYNC INPUT
This connector is used to synchronize the switching of the TPS62350 to an external clock source. Pin 1 of
J4 connects to the SYNC pin of the TPS62350. Pin 2 of J4 is connected to the ground of the TPS62350.
The SYNC input has a 1-M
Ω pulldown resistor installed on the EVM board.
