Power Management

AC Adapter and 5V Input Power Jack/Switch

The SP601 is powered from a 5V source that is connected through a 2.1mm x 5.5mm type plug (center positive). SP601 power can be turned on or off through a board mounted slide switch. When the switch is in the on position, a green LED (DS15) is illuminated.

Onboard Power Supplies

The diagram in Figure 1-30shows the power supply architecture and maximum current handling on each supply. The typical operating currents are significantly below the maximum capable. The board is normally shipped with a 15W power supply, which should be sufficient for most applications.
