Abstract
Systems and methods for charging a super-capacitor are disclosed. An exemplary method may include outputting a controllable signal, such as a pulse width modulated (PWM) signal, to control a charging circuit. The method may also include determining system voltage. The method may also include reducing a duty cycle of the controllable signal if the system voltage is in regulation, and increasing the duty cycle of the controllable signal if the system voltage is out of regulation to reduce brown-outs during charging of the super-capacitor.
