Abstract

A circuit for controlling multiple input voltages to produce a given output voltage using only a single DC-to-DC converter. Sensing of the input voltages supplied to the circuit effect automatic switching to route the applied voltages between input terminals and output terminals, and configure the feedback network selecting the output voltage of the DC-to-DC converter. The DC-to-DC converter thus configured provides required output voltages not appearing in the input supply.
