Part Number: TPS8268090 Other Parts Discussed in Thread: TPS62800 Hi TI Experts,
We need to know what is the gap ( minimum height ) under the inductor component between inductor body and substrate, please refer picture below :
The concern is…
Hi Alberto,
It's difficult to design a space saving module (via stacking the components) that is low profile. We actually did this a few years ago in the TPS8268090, but the efficiency is below your target.
However, with modern discrete DC/DCs,…
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:

Hello
I am unable to contact the original engineer that worked on that blog.
However, I have attached some references that may be helpful.
Thanks
