HI TI Expert,
Can you please help to review the schematic of TPS53915?
Thanks

Hi Allen,
My colleague will into it and will feedback to you next week.
The components values look okay. I would increase the C557 to 2.2uF. Also, consider checking the Cout capacitance against the load transient requirement, using webench on the product folder.
Review the schematic and layout recommendations in the datasheet and evm guide. The schematic does not label the power ground and quiet ground.
Care needs to be applied when laying out the pcb, connect the feedback resistor and trip resistor to the quiet ground.
see the datasheet page 41 and page 35 for agnd and pgnd connection s www.ti.com/.../tps53915.pdf
