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
the various power rails used by the components on the board.

An on-board multi-channel power monitor device (LTC2978) measures both the
voltage and current for several specific board rails. This device has the capability to
trim voltage outputs ±10%.

Table 2–40

lists the power requirements for each major component on the board.
