Abstract

Described are light emitting diode (LED) and non-LED driver systems and methods that reduce current overshoot and, deadtime, and other undesirable effects in applications such as adaptive driving beam headlamp application that negatively impact circuit parameters, including efficiency. In certain embodiments, this is accomplished by using a current clamp circuit that is controlled such as to limit an overshoot in load current, e.g., when a number of LEDs that are turned on changes.
