Secondary POL Conversion

JAS nodes should include POL conversion as needed.

POL conversion has become very popular as the voltage requirements of electronic components have continued to drop. It is quite common for many digital electronic devices to use voltages of 1.8 VDC and below. Routing high current, low voltages around a printed circuit board or between nodes is impractical due to large voltage drops, wide circuit traces and higher power consumption. Thus the secondary voltage provided by the primary converter and bussed to all the nodes is high enough to keep currents reasonably small but low enough that the point of load converters operate at very high efficiencies, typically greater than 90%. POL conversion does not preclude the generation of higher voltages with a step-up converter.
