Abstract
This disclosure relates to a voltage regulator system where duty cycle value of an input voltage is measured, where the input voltage is supplied to a regulator circuit that provides a regulated output voltage. Based on a calculated ideal duty cycle, which is derived from the measure duty cycle, a determination is made as to whether the regular circuit operational mode is to be changed to achieve greater efficiency.
