System Power for Low Voltage DC Motors

DC/DC controllers and regulators are needed for system power requirements. System power refers to the power that drives the motor itself and may be stepped down in turn to provide a power source for conversion for use by the processor core and I/O. DC/DC controllers are used here to condition the voltage supply and reduce the level of the voltage source from an external DC source.
