Abstract
A system and method for operating one or more light emitting devices is disclosed. In one example, a reference voltage input at an error amplifier receiving a feedback signal from the one or more light emitting devices is adjusted to a first higher voltage independent of a requested irradiance of the one or more light emitting devices during startup in order to accelerate startup of a switching regulator driving the one or more light emitting devices. Subsequently, upon an output of the switching regulator reaching a desired voltage, the reference voltage is adjusted based on the desired irradiance of the one or more light emitting devices.
