  • DC-DC converter with adaptive zero tracking
    Patent number: 11863073
    Abstract: A DC-DC converter includes an output terminal, a reference voltage source, an error amplifier, and a compensation circuit. The error amplifier is coupled to the output terminal and the reference voltage source. The error amplifier is configured to generate an error signal representative of a difference between a voltage at the output terminal and a reference voltage provided by the reference voltage source. The compensation circuit is coupled to the error amplifier. The compensation circuit includes a resistor, a capacitor, and a switch control circuit. The resistor is coupled to the error amplifier. The capacitor is coupled to the resistor. The switch control circuit is configured to modulate connection of the resistor to the capacitor based on a switching frequency of the DC-DC converter.
