Reference Manual
Power Supply
A laptop style DC power input provides power to the development board. The input
voltage must be in the range of 14 V to 20 V. The DC voltage is then stepped down to
various power rails used by the board components and installed into the HSMC
connectors.
An on-board multi-channel analog-to-digital converter (ADC) measures both the
voltage and current for several specific board rails. The power utilization is displayed
on a graphical user interface (GUI) that can graph power consumption versus time.
Power Distribution System
Figure 2–11 on page 2–74 shows the power distribution system on the development
board. Regulator efficiencies and sharing are reflected in the currents shown, which
are conservative absolute maximum levels.
