DC-DC buck converter board

Other Parts Discussed in Thread: UCD7230

Hi,

I want to investigate an adaption method for dc-dc converter but the design of dc-dc buck converter i designed is not good enough, in terms of noise and the interface with the DSP is not good I guess. So I need to find synchronise buck dc-dc converter development board that working with rang of 20-40 kHz and this board can connected to DSP F28335. I mean the DSP is the controller of the converter, actually I had a look to the data sheet of  UCD7230 but I don’t know if it is working with low frequency, and I don’t know if I can connected to the F28335.  

So, please if anyone can help me with this issue?

Regards

    Could I ask what it is that you are planning to power with this dc/dc converter, what is the load?

    What are your input voltage requirements for the DC/DC and what is needed for an output voltage and current?

    The UCD7230 was designed to be used at higher switching frequencies but I don't believe that there are any limitations which would prevent it from being used at these lower frequencies.

    The UCD7230 will interface with the F28335.
