Hi,

We have UCD3138PFCEVM-026 in conjunction with UCD3138CC64EVM-030. It worked fine in single phase mode. however I reprogrammed it to work in interleaved mode and now there is no output i.e . the boost is not working. I installed the appropriate jumper on the board E1-E5. I would like to go back to single phase mode however I need the original code the ic came with. my email address is hdave@naii.com.

I am not sure how come it did not program.

Hiren,

Did you receive the email I sent you on this issue? Is your power stage still not working? Please let me know. Thanks!

Regards,

Brandon Vonk

Hi Brandon,

Thank you for the code. I downloaded it to the processor and was able to go back to single phase mode. in order to recompile the code do I need CCS version 3.3? it seems the code I have for the interleaved PFC which was not correct. so I will recompile the code you sent by making the change.

Hello Brandon.

I‘m a student in an university,and I'm working on the UCD3138 Training Labs.I have compiled the code of TrainingLabs 01 and I use Fusion Digital Power Designer v1.9.78 to download the X0 file.Then the downloader window(Firmware Download) says "Download completed without error",and after few seconds,it says "No PMBus devices responded to a DEVICE_ID request".And I want to know how to solve this error.Is it still in the ROM mode?Thank you very much!My hardware is EVM 029 with a new UCD3138 chip,software is Fusion Digital Power Designer v1.9.78

Best wishes!
