• a signal input terminal;
• and
• first and second voltage converters, including first and second driving circuitry, respectively, in which:
• the first driving circuitry includes a first set of transistors coupled to the input voltage terminal, a second set of transistors coupled to the input voltage terminal, and a first output voltage terminal;

• wherein the first driving circuitry is configurable to switch between providing a first voltage at the first output voltage terminal using the first set of transistors and providing a second voltage at the first output voltage terminal using the second set of transistors based on a signal received at the signal input terminal;
• and
• wherein the second driving circuitry is configurable to switch between providing a third voltage at the second output voltage terminal using the third set of transistors and providing a fourth voltage at the second output voltage terminal using the fourth set of transistors based on the signal received at the signal input terminal.

A method comprising:

• detecting, by a controller, an activity level of a sensor that includes a set of transmit and receive components and a set of digital components;
• providing, by first driving circuitry, a power level, within a first power level range, to the set of transmit and receive components based on the detected activity level;
• and
• providing, by second driving circuitry, a power level, within a second power level range, to the set of digital components based on the detected activity level.

A method comprising:

• transmitting, by transmitting circuitry of a sensor, radar signals to a tank containing material;
• receiving, by receiving circuitry of the sensor, reflected signals resulting from the radar signals being reflected by the material in the tank;
• sensing a level of the material in the tank based on the reflected signals;
• and
• controlling, by a controller, a current provided to the sensor based on the sensed level of the material in the tank, wherein a first amount of current is provided when the sensed level is a first level and a second amount of current is provided when the sensed level is a second level, and the first level is less than the second level and the first amount of current amount is less than the second amount of current.
