Beschreibung
Zusammenfassung:	A DC-DC converter including a switching buck regulator including a first power switch connected to a first power node, a second power switch connected to a second power node, a driver configured to drive the first and second power switches, an output filtering inductor connected to a node between the first and second power switches, and an output filtering capacitor connected to the output filtering inductor, a controller configured to compensate for an output signal of the switching buck regulator in a time domain using a reference voltage, and a feed forward circuit connected between the switching buck regulator and the controller, and including a first buffer, a second buffer, an RC filter, and an adder may be provided. Accordingly, the DC-DC converter can reduce a delay of a compensation circuit, improve transient response characteristics of the switching buck regulator, and further improve the performance of the DC-DC converter.
