Claim:
1. A medical device for providing an electrical stimulation therapy for a patient, the medical device comprising: a microcontroller configured to generate a plurality of electrical pulses and a control signal; a stimulation driver coupled to the microcontroller, the stimulation driver being configured to amplify the electrical pulses into amplified electrical pulses to be delivered to the patient as a part of the electrical stimulation therapy; a battery configured to supply a first voltage; and a voltage up-converter coupled between the battery and the stimulation driver, the voltage up-converter including a charge pump; wherein: the charge pump is configured to receive the first voltage and convert, in response to the control signal from the microcontroller, the first voltage to a compliance voltage for the stimulation driver; the compliance voltage is a fraction of the first voltage; and the fraction is a non-integer value that is greater than 1.
