Abstract
A system and method to provide voltage to a device from the operating mode of an integrated circuit is disclosed. In a particular embodiment, the disclosed system includes an integrated circuit having an input/output pin and a DC-DC converter circuit that is coupled to the input/output pin and including a transistor element. The DC-DC converter circuit has a first mode of operation and a second mode of operation. In the first mode of operation, the DC-DC converter circuit performs voltage conversion and in the second mode of operation, the transistor element of the DC-DC converter circuit is used to selectively apply a voltage supply to an external module coupled to the input/output pin.
