Introduction
1.1
Requirements
To operate this EVM, connect and properly configure the following components:
A personal computer (PC) with a USB port is required to operate this EVM. The TPS650380 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 TPS650380 through the USB port. The software has been tested
with the PC requirements listed below. It may work with other operating systems and configurations,
but this has not been verified.
Personal Computer Requirements
•
Windows XP™ operating system
•
.NET 2.0 or higher
•
USB port
•
10 MB of free hard disk space
•
512 MB of RAM
USB-TO-GPIO Adapter
The USB-TO-GPIO adapter is the link that allows the PC and the EVM to communicate. One end of
the USB-TO-GPIO adapter connects to the PC with the supplied USB cable. The other end of the
USB-TO-GPIO 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-TO-GPIO adapter receives the USB command, converts the
signal to an I
2
C protocol, and sends the I
2
C signal to the TPS650380 EVM board.
Software
Texas Instruments provides software to assist in evaluating this EVM. This software can be
downloaded from the TPS650380EVM-054 Product Page, located at:
http://focus.ti.com/docs/toolsw/folders/print/TPS650380EVM-054.html
Printed-Circuit Board Assembly
The board contains the TPS650380 IC and the required external components to evaluate it as a
processor power supply solution.
