Hello,
TI offers a variety of buck controllers that may work in place of the TPS53015DGS.
As a drop-in replacement (without adjustable soft-start), I would recommend the TPS53014- https://www.ti.com/product/TPS53014
If a DCAP/DCAP2 topology is desired…
Part Number: CSD87351ZQ5D Other Parts Discussed in Thread: TPS53119 , Hi,
The customer will be using TPS53119 and CSD87351ZQ5D for 12Vin to 5Vout/10A. Webench simulation result shows that the power dissipation for CSD87351ZQ5D is 1.21W with ambient temperature…
Hi Aki,
You can get lots of single channel results on ti.com, product searching... Like TPS40195, TPS53119, TPS40075, TPS53015...
Yes, for TPS51225, the output voltages are fixed.

Xiaosen,
I think the solution is viable based on what you have listed. For the high current rail, TPS53119 would be a good cost effective alternative.

Steve,
TPS53219A is the alternative part. Also TPS53119 is a newer part with slightly different temp range.
To answer your question yes it is okay to design for higher current as long as the design considerations are taken care of.

John,
LM3485 is designed to be used with a PFET. You can look at alternate parts such as TPS53119 that has a skip mode feature at light loads.

For the VIN capacitors, the input capacitance needed is based on the amount of the input RMS current the device will see. Once the maximum DC OCL set point is determined, the input RMS current can be calculated to determine the input capacitors needed…
