Hello Pavel,
The opportunity for noise induced operational errors is high due to the long cables.
If your goal is to have it operating, running code, you may see errors.
If your goal is to simply have the system powered while you dose the radiation…
Hi Ipsit,
The LMZ22008 would be the best product for this application. It can do 6V to 20V input, 0.8V to 5.5V output, and up to 8A of output current.
For the 12V --> 5V conversion at 6A, this is 92.8% efficient. (You can run a WEBENCH design with…
Other Parts Discussed in Thread: LMZ22008 , LMZ22010 , LMZ22003 I'm using the LMZ22008, LMZ22010 and LMZ22003 in my design. I need to know what the output impedance for these devices to properly calculate my FPGA supply cap decoupling values...
Hello Kyohei,
thanks for reaching out in E2E.
Figure 9-29 and 9-30 in the datasheet are showing the output voltage ripple. The setup is as described at the beginning of section 9.2.3. Please note that the oscilloscope bandwidth was set to 20MHz in…
The filter would be placed after the main inductor of the converter & before the feedback point, like so (from Understanding, Measuring, and Reducing Output Noise in ... TI E2E support forums https://e2e.ti.com › cfs-file › __key › 3362.unders... ): …
Shinichi Inoue said: Could you please share recommended layout and test data with me?
Layout recommendations as per datasheet. As for test data, you can refer to this presentation material:

Other Parts Discussed in Thread: LM3150 Hi,
I'd like to ask about the need of external ripple injection circuit for LM3150.
According to the attached PDF file page 14,
It saids that we need the external ripple injection circuit when the output voltage…
