Level shifter circuit with integrated feedback circuit, dc-dc converter, and method

A pulse-triggered level shifter circuit comprising:

• a command circuit configured to shift a command input signal of a first voltage domain to a command output signal of a second voltage domain, wherein the command circuit comprises:
• a command input stage for receiving the command input signal,
• a command output stage for providing the command output signal;
• a feedback circuit, coupled to the command circuit, and configured to shift a feedback input signal of a third voltage domain to a feedback output signal of a forth voltage domain, wherein the feedback circuit comprises:
• a feedback input stage for receiving the command output signal as the feedback input signal, and
• a feedback output stage for providing the feedback output signal;
• wherein the command circuit and the feedback circuit are integrated into one single level shifter circuit.

A method of operating a pulse-triggered level shifter circuit, wherein a command circuit and a feedback circuit are integrated into one single level shifter circuit, and wherein at least one connection element couples the command circuit and the feedback circuit, the method comprising:

• receiving a command input signal and providing a command output signal by the command circuit;
• receiving the command output signal as the feedback input signal and providing a feedback output signal by the feedback circuit;
• and
• setting, by the at least one connection element, at least one temporally limited current pulse without using an additional pulse generator circuit.
