Abstract
A universal serial bus on-the-go (USB-OTG) power source includes a direct-current to direct-current (DC-to-DC) converter for generating a source voltage when coupled to a battery. A pulse generator generates an oscillating signal when a USB-OTG enable signal is asserted. A power supply module generates a supply voltage from the oscillating signal and the source voltage.
