Part Number: TPS55288

Hi team,

Could you please help check the schematic as below and let us know any needs to adjust/modify?

Also, there are some questions in below about the EVM user guide.

1. Does ground have to separate AGND and GND?

2. All the headers can be removed?

3. On page 7~9 in the user guide, what R and C can be changed to 0201 size?

4. On page 7, NT1~NT3 can be removed?

5. On page 7, What's C1 capacitor value range? Or that must to have 68uF? The cap can be changed to SMD cap?

Thank you!TPS55288.pdf

Dear Sir,

What is the Vin range, Vo range and output current range? The components values were determined by the those parameters.

By the way, for the customer schematic review, I prefer email review instead of the E2E review. Please accept my friendship request and contact me by email.
