Other Parts Discussed in Thread: PMP21887, TPS53688

Hello,

My customer is looking for a solution and reference design that can support  the following conditions.

  - VIN = 12V(typ), VOUT = 0.75V~1.0V, IMAX = 205A

Could you please recommend TI's best and newest soltuions and reference design?

Thank you.

    It has 12 phases for a 300A application, and I tested it at 360A steady state. See Test Report for thermal images.

    For 205Amax, I would use only 8 phases. The design has CSD95480 power stages, but I would use the newer CSD95410 power stage instead.

    If max current for thermal purposes is less than 205A, fewer phases would be needed. A good conservative target is 25A per phase. With 8 or fewer phases, the TPS53688 controller can be used instead.
