Abstract
Various embodiments of apparatuses, systems and methods for regulating the currents provided by a DCDC buck converters to an LED unit are provided. In accordance with at least one embodiment, a regulating element operable to instruct and regulate the periods during which a first switch of a driver module, used to control the operation of a buck converter module, is configured into at least one of a first operating state and a second operating state such that the maximum and minimum currents provided by the buck converter module to a load, such as an LED unit, over a given duty cycle are symmetrically disposed about an average current provided to the LED unit during the duty cycle, where the average current provided is substantially equal to a target current for the LED unit.
