USB to PMBus Adapter Quick
Start 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
• Connect the USB Mini provided between the host computer
and the USB to PMBus adapter
• Connect USB to PMBus adapter to demonstration board to
test or evaluate
• Apply input power (labeled VIN) to the demonstration board
• Using the host PC’s internet browser, connect to the
following website:
