Power Supply

The board’s power is provided through an IBM laptop style DC power input. The

input voltage must be in the range of 14 V to 20 V. The DC voltage is then stepped

down to the various power rails used by the components on the board and installed

into the HSM connectors.

Figure 2–17 shows the power distribution system, which uses current power rails as

described in “POWER SELECT Rotary Switch” on page 2–21. Regulator inefficiencies

and sharing are reflected in the currents shown.
