PS Node Local POL Conversion

The output power from the PS node is one or more secondary voltage rails that are distributed throughout the system. This distributed secondary voltage is typically a higher voltage than those required by the components on the other nodes in order to improve efficiency by minimizing losses through distribution. Each node (including the PS node) has dedicated local point-of-load (POL) power converters, which convert the secondary voltage to the voltages required by the node. Local POL conversion provides high current capability, which may be required by core power rails on higher-performance FPGAs and their supporting electronics.
