  • DC/DC converter including ultrasonic feature for use with low quiescent currents
    Patent number: 8339116
    Abstract: A buck voltage converter comprises an upper switching transistor connected between an input voltage node and a phase node. The upper switching transistor turns on and off responsive to a first drive signal. A lower switching transistor is connected between the phase node and ground. The lower switching transistor turns on and off responsive to a second drive signal. An inductor is connected the phase node and an output voltage node. Control circuitry generates the first drive signal and the second drive signal responsive to a feedback voltage monitored at the output voltage node and a phase at the phase node.
