Part Number: TPS65910
Other Parts Discussed in Thread: AM3352

Hi,

One of my customer is willing to use TI's TPS65910 for their network application.

They ask to TI if there's any problem on their schematic.

Please help us.

thanks,

Hi TS,

Which processor variant is this for? I will perform the review tomorrow but it helps to know which processor to ensure that it is connected properly.

Hi TS,

Thank you for providing the context.

Note that the schematic checklist is available here.

My notes:

We recommend 2.2 uH for the SWIO, SW1 and SW2 inductors.
We recommend grounding OSC32KIN when unused.
We recommend 4.7 uH for the VDD3 inductor
How is the PMIC enabled? I am guessing there is a push-button connected to EXT_PWRON which is not shown, but if not then there is no power-on enable condition (see page 46 / 47 of datasheet).
