The power supply circuit will provide necessary power requirements for the AMD. Design
requirement is 5 VDC for the microcontroller and motor controller. Additionally, 12V is
necessary for the motor. Current requirements will be dictated mainly by the motor controller
design; while the current requirement for the microcontroller is in the range of 100mA. Also, the
power supply may require battery backup to avoid loss of user input selections and time keeping
functions.
