MODULATING SUPPLY VOLTAGE GENERATED BY VOLTAGE REGULATOR FOR TRANSMISSION OF DATA AND POWER

An apparatus for generating an output voltage including a microcontroller unit (MCU) configured to selectively generate a data modulating signal; and a voltage regulator configured to generate an output voltage modulated based on the data modulating signal. Another aspect relates to a method of generating an output voltage comprising selectively generating a data modulating signal; and bucking and boosting an output voltage based on the data modulating signal. An additional aspect relates to an apparatus for generating an output voltage comprising means to selectively generate a data modulating signal, and means for bucking and boosting an output voltage based on the data modulating signal.
