Abstract:
A boost regulator system for regulating one or more output voltages includes, a first pump element coupled to receive a first input voltage, a first switching device coupled to the first pump element, the first switching device causing a finite amount of energy to be stored in the first pump element in response to a first control signal. The system further includes, a first capacitor coupled to the first pump element and the first switching device, the first capacitor storing the finite amount of energy and generating a first output voltage in response to the finite amount of energy. A boost controller (BC) coupled to receive the first output voltage, the boost controller further configured to regulate the first output voltage by generating the first control signal. The system further includes, a second switching device coupled to a second capacitor, the second switching device further causing a second voltage to develop across the second capacitor in response to a second control signal, a third capacitor coupled to the first pump element and the second switching device, the third capacitor further generating a third output voltage in response to the finite amount of energy, and a linear controller (LC) coupled to receive the third output voltage, the BC further configured to regulate the third output voltage by generating the second control signal.
