Power Conversion

The input power for RP nodes is provided by a single voltage rail that is distributed throughout the system. This distributed voltage is typically a higher voltage than those required by the components on the board (typically +5 volts) in order to improve efficiency by minimizing losses through distribution. Each node has local, dedicated point-of-load (POL) power converters which convert the input power to voltages required by the RP electronics. Local POL conversion provides high current capability, which may be required by core power rails on higher-performance FPGAs and their supporting electronics.

POL power conversion is discussed in more detail in the Electrical Specification.
