Abstract

Systems, methods, and devices implement direct current (DC)-DC converters having fast wake up times and low ripple effects. Methods include determining a DC-DC converter is to be transitioned from an operational mode to a low power mode, and storing a voltage at an input of a comparator coupled to an input of a charge pump, the voltage being stored in a feedback capacitor of a feedback regulation loop. The methods further include uncoupling a voltage trimming circuit from the input of the comparator, and maintaining, at least in part, the stored voltage at the feedback capacitor during the low power mode.
