Abstract
The present disclosure describes apparatuses and techniques of fast transient response for switching power regulators. In some aspects, a capacitor is disconnected from an output of a feedback amplifier of a switching power regulator that is operating in a discontinuous mode. This can be effective to prevent a voltage of the capacitor from discharging while the switching power regulator operates in the discontinuous mode. Responsive to the switching power regulator transitioning from the discontinuous mode to a continuous mode to provide an increased amount of current, the capacitor is connected to the output of the feedback amplifier. Connecting the non-discharged capacitor can be effective to enable the switching power regulator to provide the increased amount of current to the load more quickly.
