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. The mainframe supplies a small amount of
3.3 V for the processor interface, but the bulk of the 3.3 V used on the board
is pr
oduced by the switching supply.
There are also 1.8 V and 1.2 V s upplies, which are used for the memory and
FPG
A cores.
