Hi,

Can you please help providing the step-by-step to enable the output voltage for IR38263 using PMBus? I'm trying to help a customer but as we don't have the eval-kit yet, we couldn't progress over a remote conference call.

We are using the PowIR GUI with USB005 dongle, the license is all set. By loading the default config file and selecting PVID mode the voltage is correct set and we can verify at the tool, thus the communication interface seems to be working, but when changing to PMBus and sending the commands, the output is always zero.

Can you please describe the procedures to modify and enable the output voltage using the GUI? We are probaly missing something.

If you have capability to provide some screenshots, probably it will help.

I am repairing a video card and it is necessary to read the XDPE132G5D chip being in use on the graphics card. I can read the IR35217 chip but with the OpenPower tool the only XDP chip option to read is the XDPE162G5.

What tool do I need to read the XDPE132G5D?

Thank you very much for your support!

Hello, please tell me how to choose or calculate the KFQ coefficient. Is there any dependency for its selection?

Hi 

we are looking a simple cost effective buck converter

Input DC Is +55VDC

output DC is 35VDC, load current at 35VDC is 3A.

can you suggest a cost effective simple solution.

Hello,

I use the TLE8366EV like that to generate a 5V from a 12V

I calculated the resistance values using this equation

But I don't have 0.6V on pin FB so I don't have an output of 5V (but only 3.73V)

Thanks

Hello,

Why don't PMIC(TLF35584 ) datasheets list the operating temperature range?
Can Infineon specify the operating temperature range for TLF35584?

Best regards,
