Abstract
A driver circuit for driving one or more loads in a controlled manner includes multiple operational modes. In one mode, bypass switching may be used to adjust a drive signal applied to the one or more loads. In another mode, a DC-DC converter may be used to adjust the drive signal applied to the one or more loads. In at least one embodiment, the driver circuit is a light emitting diode driver circuit.
