We are trying to run TLF35585 in standalone (without microcontroller) by pulling MPS pin high (5V).
We have connected ENA and WAK directly to input supply.
And connected MPS signal to watchdog disable signal (5V)
At QST (standby) output should get 5V continuous.
BUT - we are only getting pulses like below (1mS width, 20mS interval) - similar waveforms are seen in all outputs.
Can you please suggest what is wrong here?

Hi,
We want to use WLC1115 in our project with others components (e.g LCD, microcontroller....). It is possible to use the same GND? Could you please advise?
Show LessIt is cheaper to sense the switch current as compared to the inductor current in the Boost PFC. How we can reconstruct the inductor current by sensing the switch current?
Show LessI am using a IR38063 to power my Intel Arria 10 Design... The initial design was based on the IR38063 Demo Board. I am seeing what seems like excessive ripple on the output. I have used the SupIR_Buck Design Spreadsheet (attached) to modify the original design to lower the max current (8-10A) and to try and represent the number of capacitors in my circuit. (FPGA required) The spreadsheet shows a very good result as far as ripple but the real world design seems to have short spikes on Vout. I am also getting the VOUT_UV_FAULT at .83V which does seem to imply that there is indeed some significant ripple out output. In trying to tune this I have tried different inductors and then swapped the compensator components (as the spreadsheet indicated) and some of the bulk output capacitors to try and minimize ripple (first page line 119) and maximize phase margin (second page line 101). I unfortunately cannot add all the different type caps that are in my system since the tool only allows 3 different values on the output. Any help as to where to focus would be appreciated. Hints as to how to pick an inductor and numbers of bulk caps would also be appreciated.

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!
Show LessHi
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.

Hi Infineon community,
I need to know if the is an EOL document for the ASF461 that mentions the new recommended part to be replaced. It is an International Rectifier EMI filter
Show LessDoes anyone have failure rate (FIT, 55C/60%CL) data for TLE94713ESV33XUMA1?
