TPS543C20: Request for reference design

Abhijith TP

Part Number: TPS543C20

Dear Team,

We are planning to implement the "TPS543C20RVFT" Stackable regulator with Master & Slave configuration for generating 0.72V, 40A with 12V as input.

As I was going through the Web Bench Tool, the design examples for this part is not available.

Can you please provide the example design for generating voltage and ampere as per the above mentioned requirements?

I have checked the EVM design of https://www.ti.com/tool/TPS543C20EVM-054 part, but our requirement is a synchronous/master-slave circuit

Regards,

Abhijith

Have you looked at the 12V to 0.9V @ 80A 2-phase EVM - https://www.ti.com/tool/TPS543C20EVM-869 ?

It can be modified for for a 0.72V output, and for a 20A/phase full load, lower current rating inductors could be selected, but it does provide a good reference design starting point.

If you intend to use WeBench, I would recommend dividing the design in half (20A load current) for power stage and compensation selection, then combining he outputs (2x the single phase output capacitance)
