B.4 Power Supply
The MiniCore requires a regulated 3.15 V – 3.45 V DC power source to operate. Depending on
the amount of current required by the application, different regulators can be used to supply this
voltage.
The Interface Board has an onboard +3.3 V linear regulator. The Interface Board is protected
against reverse polarity by a Shottky diode at D3 as shown in Figure B-4.
Figure B-4. Interface Board Power Supply
Power may be supplied to the Interface Board either via the mini USB connector at J5 or through
the power supply jack J6. When a separate power supply is used, the chip at U4 disables power
from the mini USB connector, which continues to supply power only to the USB interface chip.
Diodes at D1 and D2 prevent power from going back to the other power supply that is not supply-
ing power. A separate power supply is required whenever the Interface Board is not connected to
the PC.
A jumper on header JP2 controls the current limiting applied to the power drawn via the mini
USB connector — the current is nominally limited to 500 mA when no jumper is installed
(default), and is nominally limited to 700 mA when a jumper is installed.
