Part Number: MSP430FR2475
Other Parts Discussed in Thread: TPS56528

Tool/software:

Hello TI team,

We are designing a product based on MSP430FR2475 MCU.

We have used TI buck, TI USB PD controller with this MCU based design.

Please check the consolidated schematic, and share your feedback

Specific attention needed for Buck converter design to reduce ripple current and voltage. (inductor size is a constraint, not to increase more than +/-10% of existing size)

Hi Garmia,

I do not see an attached schematic. I suggest sending the schematic to your TI Sales Rep or Field Applications Engineer and they can funnel to all the appropriate teams (I would only be able to cover the MSP430FR2475 relevant connections).

Regards,
Luke

I am not able to insert file here, i have shared email for this issue to TI, I can loop you in there and share file.

Can you give your mail ID?

Hello Luke,

I looked you in the mal thread, pls check the attached schematic on first email of the thread and share your feedback.

Additionally need your help on TPS56528 we bench simulation. Same issue we are discussing our email but there is no fruitful response we are getting.

Issue is basically webench simulation is giving wrong switcher frequency, datasheet only mentions 650kHz supported but report is generated for 790kHz.

We shall need to share the buck simulation report to our customer for our usecase but its pending since more than a week now.

Request you to check and let me know if any information needed from my side.

Hi Garima,

I had replied to your email.

For the TPS56528, I recommend creating another E2E post for that information if you're not already handling it via email with a TIer. I will only be able to help with regards to the MSP part.

Regards,
Luke
