User’s Manual
user-supplied regulated +5 V DC is supplied to the PowerCore module from the motherboard—the
+5 V is regulated down to +3.45 V for driving the nominal 3.3 V components on the PowerCore;
the motherboard can draw from the 3.45 V supply
user-supplied unregulated DC (8–40 V) is supplied to the PowerCore module from the mother-
board or via the locking power connector at J3—requires onboard +5 V switching regulator @ 1 A
or 2 A maximum output; the +5 V is regulated down to +3.45 V for driving the nominal 3.3 V com-
ponents on the PowerCore; the motherboard can draw from both the 3.45 V and the +5 V regulated
supplies
AC from two-lead transformer is supplied to the PowerCore module that has half-wave rectifier
and filtering capacitor, includes zero-crossover detection to synchronize software drivers for triac
support, two-lead transformer with untapped secondary winding may be used—the resulting DC
then passes to the onboard +5 V switching regulator @ 1 A or 2 A maximum output, and is further
regulated to +3.45 V; additional filtering capacitors may be needed on motherboard if high unregu-
lated DC current will be drawn
AC from three-lead center-tapped transformer is supplied to the PowerCore module that has full-
wave rectifier and filtering capacitor, includes zero-crossover detection to synchronize software
drivers for triac support, transformer with tapped secondary winding required—the resulting DC
then passes to the onboard +5 V switching regulator @ 1 A or 2 A maximum output, and is further
regulated to +3.45 V; additional filtering capacitors may be needed on motherboard if high unregu-
lated DC current will be drawn
AC from two-lead transformer is supplied to the PowerCore module that has full-wave bridge recti-
fier and filtering capacitor, no zero-crossover detection or triac support, transformer with untapped
secondary winding may be used—the resulting DC then passes to the onboard +5 V switching reg-
ulator @ 1 A or 2 A maximum output, and is further regulated to +3.45 V; additional filtering
capacitors may be needed on motherboard if high unregulated DC current will be drawn
