    • A charge pump (200) can be used with a bus-powered device connected to a bus. The charge pump (200) comprises a power connection (210) from the bus carrying a DC power signal constrained to not exceed a given current limit and a given voltage limit, a DC-to-DC step-down voltage converter (300), a capacitor (C1), and a DC-to-DC step-up voltage converter (400). The step-down converter (300) has an input connected to the power connection (210) and produces an intermediate signal having a voltage the same or less than the voltage of the power signal. The capacitor (C1) is connected to the output of the step-down converter (300). The step-up converter (400) has an input connected to the output of the step-down converter (300) and to the capacitor (C1), and produces a final output signal having a voltage greater than the given voltage limit. The output of the step-up converter (400) is connected to and provides DC power to the device.
