Abstract
In one embodiment, a charge-pump controller is formed to control a value of current supplied to a load. One embodiment of a method of forming a charge pump controller may include configuring no more than three alternately switched switches of the charge pump controller to couple to a capacitor wherein the no more than three alternately switched switches are configured to couple the capacitor in a charging configuration during a first time period and to couple the capacitor to supply a current to an LED during a second time period. Another embodiment of the method may include configuring the charge pump controller to receive a sense signal that is representative of the current and to regulate the current, substantially to a first value.
