Hello Bruce,
It sounds like the it is caused by over current condition. There is no way of disabling the over current protection function. Are you using the EVM with LC filter for your inductive load? When designing the LC filter, the load must be…
Hi Ethan,
If it is about general loop calculations of a flyback design, an app note like this might be helpful: /cfs-file/__key/communityserver-discussions-components-files/196/0412.slup340.pdf
Another calculation tool using these formular is the…
Thank you for the quick response Brigitte.
I appreciate the quickstart calculator file, I didn't run across this resource in my design. I'll attach the filled form at the bottom. A few things I've noticed:
The COMP values are different, especially…
Hello Steve,
We have this board design as a reference that converts RGB (926 output) or LVDS (948 output) to DVI (HDMI). Would this work for your application?

Hi Damian,
Work In progress!
I have 2 issues :
1- I'm using GPIO the Pin 15 for enable a LDO regulator (TPS70930DBVR : Texas Instrument). Without this composant I haven't 1.51 V. So my first issue are a flowing current through EN input to IN input…
Hello Helmuth
You can simulate your design using PSPICE. The model is available at https://www.ti.com/lit/zip/snvmcd7
To check stability, you can use Power Stage Designer https://www.ti.com/tool/POWERSTAGE-DESIGNER and select CMC Inverting Buck-Boost…
HI Kevin,
At 2phase mode, the part is using channel 1 loop only. The channel 2 loop is disabled.
So the bode plot of 2phase deisgn can be measured on channel 1.
Please refer to the attached user guide page 14 on how to measure bode plot on channel…
Hello Marc,
These two products are very similar but I would suggest DS90CF386 due to the more flexible PCLK range.
Also we have actually created the application you are describing before using DS90CF386 and TFP410. It's not orderable but you can find…
Hi Nigel,
Since we have limited information about your system and measurement setup, it is difficult to have a conclusion from your results.
Please check the application note attached.

Hi GuoJie,
Both LP8758-C5 and LP8758-C3 have not been mass-produced yet.
Please find their preliminary datasheet attached below:
