Are there configuration methods other than PMBus for the UCD9222?

Other Parts Discussed in Thread: UCD7242, UCD9222, TMS320C6678

We have a design using two TMS320C6678, and I know UCD9222 and UCD7242 should be used. 

But we donot know how to configue the UCD9222 using PMBus. Can the UCD9222 work well without

using PMBus? Thank you very much.

    The UCD9222 controller is a very flexible device which can be used in widely different applications.  To achieve this type of operation it has a number of configurable parameters which need to be set prior to it functioning in a sepcific application.  The configuration is created using the Fusion Digital Power Designer software, a free download from the TI website, and is typically loaded into a device through the PMBus interface during product development, although there are several additional methods which can be used to load this configuration.  Including JTAG and the capability to write a hex file directly to the data flash, these methods require their source file to be written out of a controller that has already been configured.

    There is a document called Configuration Programming of UCD Deviceswhich can be found in the Documentation & Help Center of the Fusion Digital Power Designer GUI which explains the options available for applying the configuration.  Some customers have a distributor load the configuration prior to assembly, others have their CM/internal manufacturing load the configuration.  A project file (.XML) is required no matter how the controller is configured and should be generated from the Fusion Digital Power Designer GUI by the hardware designers.
