TPS65265: Could you review schematic of TPS65265 and LM26480-Q1.

Hi Dexter,

For TPS65265 part, there are some comments below:

1. Suggest to add a 1uF or 0.1uF cap to PVIN and GND. And place the cap as close as possible to PVIN on layout.

2. For Buck1 and 2, 4.7uH inductance (L6 and L7) is okay for your application.

3. Change R63 and R64 to 6.8K, R65 to 10K.

4. EN pin absolute maximum ratings voltage is 7V. But in your SCH, the EN pin voltage is 2/3*12V=8V which is not acceptable. You can change R81=20K, R86=10K.

5. C89=10nF is okay.

And for LM26480-Q1, you should submit a new thread only with LM26480-Q1 and default application engineer will support you. 

Thanks,

Lishuang
