EVAL-CED1Z
POWER SUPPLIES
The CED board provides multiple power supplies that are made
available for use with connected boards. A single 7V supply is
required for the CED board and this is used to power the board
itself and the supplies for boards connected to it. A resettable
2A fuse limits the current that can be drawn from the supply
thus limiting the power consumption of the CED and any
attached boards.
On it’s own without any converter boards attached, the idle
current of the CED is approximately 220 mA. When accessing
SRAM for example, the current drawn by the CED board itself
can increase significantly. Users designing boards to operate
with the CED that wish to use the supplies provided must bear
in mind the total available power when calculating their power
requirements.
Table 8. Power Supplies
Preliminary Technical Data
While the supplies generated on the CED are kept as clean as
possible, designers of boards connected to the CED must ensure
that all devices and supplies are adequately decoupled. This will
prevent noise being fed back onto the power supplies of the
CED. Excessive noise introduced on to the power supplies may
cause the CED or attached boards to malfunction.
The voltage and current ratings of the supplies listed in Table 8
are defined to be absolute maximum limits. While fuses and
thermal overload protection have been provided in the power
supply circuitry, attempting to draw more current from a
particular supply or exceeding the total power available from a
combination of supplies may cause damage to the CED board.
