According to different embodiments of the present invention, various methods, devices and systems are described for managing power in charge pumps in a non-volatile memory system having a high voltage charge pump and associated regulator. A method includes the following operations, receiving an operation command corresponding to an operation, pumping up a charge pump output voltage to a desired output voltage, turning off the regulator and the charge pump when the output voltage is approximately the desired output voltage compensating for charge sharing by turning on the charge pump and setting a pump clock rate to a slow clock rate in order to avoid overshooting the desired output voltage by the charge pump while the operation is being carried out, and compensating for junction leakage by turning on the regulator and the charge pump until the charge pump output voltage is the desired output voltage.
