Abstract
A charge pump includes first and second multiplier stages including first and second capacitor in series with an input node, a final multiplier stage including an output capacitor in series with the second capacitor and an output node, and pre-charge circuitry. The pre-charge circuitry is configured to charge the output capacitor to a first level during an initial phase of a charging operation, wherein the first level is equal to a supply voltage of the data storage system, and decouple a charging path of the pre-charge circuitry from the output capacitor in response to the output capacitor being charged to the first level. The first and second multiplier stages are configured to increase the charge of the output capacitor to second and third levels higher than the first level during second and third phases of the charging operation.
