Abstract
A method of driving a power stage configured to provide both a positive output voltage higher than a first potential to a positive output and a negative output voltage to a negative output includes generating a first control signal and a second control signal, and initiating a charging phase, a first duty cycle of the first control signal controlling an amount of energy to be accumulated. The method further includes initiating a first discharging phase of discharging a second amount of energy the positive output and the negative output, based on a simultaneous monitoring of the first control signal and the second control signal, the amount of energy to be discharged being controlled via a second duty cycle of the second control signal.
