B.3 Power Supply
The RCM5600W 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 pro-
tected 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 supplying 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 700 mA when a jumper is
installed (default), and is nominally limited to 500 mA when no jumper is installed.
