Abstract
A method includes activating a transistor providing current to a load via an inductor based on values stored at a first timer and at a second timer. The second timer is enabled based a value of a current conducted at the inductor and based on a value of a reference current. The transistor is deactivated in response to determining that a measurement of time elapsed at the first timer is a predetermined multiple of the second measurement of time.
