1 Introduction
The purpose of this manual is to describe the functionality and contents of the Rohm
Semiconductor Power Module from Avnet Electronics Marketing.
instructions for operating the board, descriptions of the hardware features and explanations of
the header signals and functionality.
1.1 Description
The Power Module is designed to be used with the Avnet Mini-Module Plus development
system, or any system that meets the mechanical interconnect, pinout, voltage and current
requirements set forth in this document. The power module operates off a 12VDC input
provided from the target baseboard. The following table shows the output voltages generated
by the power module, as well as the voltage banks each rail is tied to through the baseboard
when used in the Mini-Module Plus system.

1.2 Features
The Power Module provides a complete power solution through the use of 3 headers.
headers are used to provide power between the Avnet Power Module and the target board. The
rd

header is used to provide access to remote sensing for increased regulation accuracy.
There is one configurable supply provided on the board which is selectable to be either 1.5V
output or 1.35V output. This supply configurability allows the Power Module to work with the
Mini-Module Plus system, supporting Mini Module cards populated with either 1.5V or 1.35V
DDR3 memory.
