DC Power Input Jack (J1)
A 9-20 Volt (V) DC input is provided by a right-angle 2.5 mm power jack
with a 5.5mm barrel. Two switching power supplies are used to provide
the incoming DC voltage, which is regulated down to 6 V, 3.3 V, and 1.8 V
by three switching power supplies. From these voltages all other on-
board voltages are generated.
Table 2–34 lists the power-supply specifications.
