Classification: CPC H  Y | IPC H

Claim 7:
8. A DC-DC converter, comprising:
an error amplifier coupled to an output terminal and a reference voltage source, and configured to provide an error signal representative of a difference between a voltage at the output terminal and a reference voltage provided by the reference voltage source;
a compensation circuit that includes:
a first resistor coupled to the error amplifier;
a first switch coupled between the first resistor and a capacitor, and having a first control terminal;
a second resistor coupled to the error amplifier; and
a second switch coupled between the second resistor and the capacitor, and having a second control terminal; and

a switch control circuit coupled to the first control terminal and to the second control terminal, and configured to modulate connection of the first resistor to the capacitor and connection of the second resistor to the capacitor responsive to a switching frequency of the DC-DC converter.
