Power supplies
There are three switching supplies, and several linear supplies in the module.
Most of the power for the module comes in as 5 V and is converted to the voltage
needed by the switching supplies. Themainframesuppliesasmallamountof
3.3 V
for the processor interface, but the bulk of the 3.3 V used on the board
is produced by the switching supply.
The
re are also 1.8 V and 1.2 V supplies, which are used for the memory and
FPGA cores.
