FPGA Power
Hello all,
I use Spartan3 400k gates FPGA for a design, the NSC datasheet said that the Iint(internal)_1.2V for this chip is 0.2 to 3(max), but Xilinx datasheet said nothing about the internal current.
And I found a ref design provided by Xilinx use a 1A regulator, shall I choose the same one, and what shall I consider for FPGA internal power first? The 3A LDO regulator is too expensive, and I am not familiar with the switch regulator.
Regards,
Davy Zhu
