USB to PMBus™ Adapter User Guide

The Intersil USB to PMBus Adapter (often referred to as a

“dongle”) is used to connect a demonstration board with a

PMBus interface to a PC. The USB to PMBus

adapter is

powered from the USB output of the host PC. The USB

interface utilizes the USB Mini format, and the output uses a

standard 2 row, 6 pin header on 0.100 inch centers. The

PMBus command set is accessed by using the

PowerNavigator™ evaluation software from a PC running

Microsoft Windows. PowerNavigator software is downloaded

from the Intersil website using the following link:

http://www.intersil.com/powernavigator.html
