Abstract
A load driving circuit includes a switch circuit and a linear circuit connected in series. The switch circuit has a switching transistor and converts an input voltage into a first output voltage. The linear circuit has a linear device and provides a driving voltage and a driving current for driving the load. The driving circuit controls the switching transistor according to a feedback signal indicative of conducting state of the linear device.
