Power conversion circuitry 242 includes circuitry that converts power from one level to another. Multiple instances of power conversion circuitry 242 may be used to provide the different power levels needed for the components within system 205. One or more instances of power conversion circuitry 242 can be operative to convert a signal supplied by power source 240 to a different signal. Such instances of power conversion circuitry 242 can exist in the form of buck converters or boost converters. For example, alarm 234 may require a higher operating voltage than high power wireless communications circuitry 212, which may require a higher operating voltage than processor 210, such that all required voltages are different than the voltage supplied by power source 240. Thus, as can be appreciated in this example, at least three different instances of power conversion circuitry 242 are required.
High quality power circuitry 243 is operative to condition a signal supplied from a particular instance of power conversion circuitry 242 (e.g., a buck converter) to another signal. High quality power circuitry 243 may exist in the form of a low-dropout regulator. The low-dropout regulator may be able to provide a higher quality signal than that provided by power conversion circuitry 242. Thus, certain components may be provided with “higher” quality power than other components. For example, certain safety sensors 221 such as smoke detectors and CO sensors may require a relatively stable voltage in order to operate properly.
