Abstract
A medical device for providing an electrical stimulation therapy for a patient includes a microcontroller configured to generate a plurality of electrical pulses and a control signal. The medical device includes a stimulation driver coupled to the microcontroller. The stimulation driver is configured to amplify the electrical pulses into amplified electrical pulses to be delivered to the patient as a part of the electrical stimulation therapy. The medical device includes a battery configured to supply a first voltage. The medical device includes a voltage up-converter coupled between the battery and the stimulation driver. The voltage up-converter is configured to 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 greater than 1.
