Abstract
Illumination driver circuit for using in an imaging-based barcode reader is configured to provide the driving current for the illumination source with a Buck regulator when the driving current is above a threshold current value and to provide the driving current for the illumination source with a linear regulator when the driving current is not above the threshold current value. The threshold current value is substantially close to the smallest current the Buck regulator operative to provide when operating in a continuous mode.
