1.5.On-Board Power Supply

There is an on-board high-efficiency DC-DC power converter that supplies +2.5V and +3.3V power to the board from the VME 5V supply. The circuit efficiency is approximately 90%. The +3.3V supply is available to the PEM and PMC sites, as well as +5V and ±12V. Up to 16.5 Watts is available from the +3.3V supply for the PEM and PMC sites. The combined +3.3V current consumption of modules on these sites must not exceed 5 Amps.

When adding modules to the Monaco board, ensure that the power requirements for the modules are within the specified limits, and that the system power supply and cooling are sufficient to meet the added requirements.
