ABSTRACT:
The invention provides a switching converter comprising as few as two high-side switching transistors and a low-side rectifying device, along with a control circuit. The switching converter is capable of operating from a main supply source or an auxiliary supply source. The invention further includes a method for producing a regulated voltage from a first supply voltage and a second supply voltage via the two high-side switching transistors and a low-side rectifying device.
