D.1.1 Power-Supply Options
Five power-supply options are available for the PowerCore modules. In two of the
options, either regulated or unregulated DC power comes to header J4 on the PowerCore
from the user’s motherboard. In the three remaining options, AC power comes either to
header J4 on the PowerCore from the user’s motherboard, or the AC power comes directly
to the PowerCore module via the polarized locking connector at J3.
Option 1—Regulated +5 V DC
Regulated +5 V (±5%) DC power must be
supplied to the PowerCore module via pins
5 and 6 of header J4 (the locking connector
at J3 is not stuffed when you select this
option). There is always a +3.45 V DC
linear voltage regulator on PowerCore
modules to supply +3.45 V DC.
With this option, the maximum power is
limited by the traces on the PowerCore module to 2 A at 5 V, which includes the power
consumed by the +3.45 V and +5 V onboard PowerCore circuits. The 3.45 V regulator can
pass a maximum of 700 mA. The PowerCore will require 150–400 mA at 3.45 V depending
on the clock speed and other options.
This power-supply option does not have the AC zero-crossover detection circuit used for
triac support.
Option 2—Unregulated DC
Unregulated DC power is supplied to the PowerCore module via pins 1 and 5 of header J4
(the locking connector at J3 is not stuffed when you select this option).
The selection of the +5 V regulator determines the voltage range for the unregulated DC
input power as follows.
• 8–43 V DC for 2 A regulator option
• 9–40 V DC for 1 A regulator option
The power consumed by the onboard PowerCore circuits is 150–400 mA at +3.45 V
depending on the clock speed and other options. This power-supply option does not
support the AC zero-crossover detection circuit.
