Abstract
To conserve power when regulating the output voltage (Vo) of a power converter, no adjustment is made to the converter's pulse width modulation times (Tp, Ts) even if the output voltage is off target (Vtar), provided that the output voltage does not change or is moving towards the target voltage. In some embodiments, the output voltage is not allowed to stay off target for more than a predetermined length of time. In some embodiments, the minimal adjustments are always large enough to overcome ringing ().
