Introduction
The PMBus™-USB Adapter (I2C-ADAPTER-A00) allows users to communicate with PMBus-version Vicor
power modules through the signal pins. A PMBus control interface is provided for digital management
and access to telemetry monitoring offered by the product. The PMBus to USB Adapter converts the
PMBus to USB communication protocol by an internal isolated controller that allows users to easily
connect to a host PC (no driver installation required on Windows). A GUI, available for download on the
Vicor website, is provided for users to easily monitor and control the power module.
The PMBus interface of a VIA
™
, a dedicated Digital Supervisor or Point-of-Load Isolator is used for
communication purposes with the provided GUI installed on the user’s PC.
The PMBus interface of a VIA, Digital Supervisor or PLI allows users to read and write into the status
configuration registers of the module, monitor faults and obtain other additional device information.
The PMBus-USB adapter provides the ability to demonstrate the PMBus digital interface offered on
select Vicor products in an evaluation environment.
