Classification: CPC H | IPC H

Claim 17:
18. A DC-DC converter, comprising:
a switching buck regulator including a driver configured to output a switching signal for driving a first power switch and a second power switch based on a driving signal, the switching buck regulator configured to output a first output signal;
a circuit connected to the switching buck regulator, the circuit including a first buffer, an RC filter, a second buffer, and an adder sequentially on a path, the circuit configured to output the first output signal together with a second output signal using the adder; and
a controller including a voltage controlled delay line connected to a first voltage controlled oscillator and a phase detector connected to a second voltage controlled oscillator, the controller configured to convert the first output signal and the second output signal into a time domain, and generate the driving signal based on at least one of the converted first output signal or the converted second output signal.
