Abstract
A controller including a switch, a first module, a second module, and a control module. The switch receives current from an inductor and bypasses a portion of the current from being received by a load. The switch is cycled between a first state and a second state at a frequency. The first module, for a first cycle of the switch, determines a first amount of time the switch is in the first state. The second module, based on the first amount of time, determines a second amount of time for a level of the current to decrease to a predetermined level. The second amount of time begins during the first cycle and when the switch transitions from the first state to the second state. The control module, based on the second amount of time and prior to the current decreasing to the predetermined level, changes the frequency of the switch.
