TPS53667: TPS53667 schematic review

Gary Teng

Part Number: TPS53667

Hi all,

My customer has a new project using TPS53667 in their FPGA power application. Would you please helping to check it? Generally they follow EVM's design and just want to confirm it. Thanks for your kindly help.

Regards,

Gary Teng

Hi Gary,

We should need all details like Vboot, IMAX, ITDC..etc to confirm all resistors. or please share TPS53667 design tool which customer used for selecting resistors.

Thanks.

Rama.

Hi Rama,

Each rail IOUT_MAX are 30A.

And IOUT_TDC(thermal design current) TBD (>35A)

I think customer follow EVM's design. But I'll check with them soon.

Hi Gary,

If IOUT_MAX is 30A for each rail, then 1-phase is ok. But Schematic shows each rail has 6-phases.

Please check with customer and update.

Thanks.

Rama.
