Claim of US Patent No. 10,468,910

1. An apparatus for driving a load, the apparatus comprising: an input configured to, in a first state, receive an input signal, an output configured to, in the first state, provide a first output signal to a series arrangement of the load and a source, wherein the first output signal is configured to feed the load and to charge the source with input power provided via the input signal, and a converter comprising a conductor-switch, a first diode and an inductor, the converter configured to, in a second state different from the first state, convert a source signal from the source into a second output signal destined for the load, wherein the second output signal is configured to feed the load with source power provided by the source, and wherein the converter is further configured to regulate a value of the first output signal by at least alternating the conductor-switch between a first mode and a second mode, such that in the first mode the converter bypasses the series arrangement, wherein in the first mode, the converter couples the inductor and the source for charging the inductor, and in the second mode, the inductor after being charged provides the second output signal to the load;wherein the input comprises first and second input terminals, wherein the output comprises first and second output terminals configured to be coupled to the load and third and fourth output terminals configured to be coupled to the source, and wherein a first contact of the inductor is coupled to the first input terminal, wherein a second contact of the inductor is coupled to a first contact of the first diode and to a first contact of the converter-switch, wherein a second contact of the first diode is coupled to the first output terminal, wherein a second contact of the converter-switch is coupled to the fourth output terminal and to the second input terminal, wherein the third output terminal is coupled to a first contact of a second diode and to the second output terminal, and wherein a second contact of the second diode is coupled to the first input terminal.
