2.11 Power
2.11.1 Primary Power Input
The board’s primary input is through a 12V barrel jack. A compatible AC/DC converter will have a
2.5mm inner diameter, 5.5mm outer diameter, center positive connection.
The total power budget is based on 4A from an AC/DC wall wart supply. This rail is protected
with a TE 0603SFF600F/24-2.
A 10mΩ, 1W current sense resistor exists in series with the 12V input power supply. Header J21
straddles this resistor to measure the voltage across this resistor for calculating ZedBoard power.
2.11.2 On/Off Switch
ZedBoard includes an On/Off switch, SW8, to gate 12V. . When SW8 is in the OFF position, 12V
is disconnected from the board.
2.11.3 Regulators
The following Maxim power solution provides the power rails of the ZedBoard.
