TPS650864: Power management forum

Part Number: TPS650864

Hi,

If TPS65086401 is used to power Xilinx Zynq US+ 3CG device, the VCCINT specifications are:

VCCINT: 0.825V (min), 0.85V (typ.), 0.876V (max.)

However, what is the TPS65086401 BUCK2 specification for 0.85V output?

Is it with the tolerance of -30mV / +40mV?

But if in this case, would it violates the Xilinx Zynq US+ specifications?

    Hi,

    Thank you for your question. It is important to note that this spec covers a wide range of operating conditions(-40C to 85C) as well as a wide Vin range (5.6V to 21V). Under typical conditions, the BUCK2 output range may perform better.

    Additionally, this product is quite competitive and historically has been successfully used with the Xilinx Zynq Ultrascale+ portfolio.

    Thanks,

    Daniel W
