Abstract

The present disclosure describes apparatuses and techniques of fast transient response for switching power regulators. In some aspects, a detection is made of a switching regulator's transition to a continuous mode of operation to provide current to a load. In response to the transition, a predefined current limit of the switching regulator's current-limit circuitry is increased effective to enable the switching regulator to draw an amount of input current that exceeds the predefined current limit. The switching regulator is then permitted to operate with the increased current limit for a predetermined number of cycles, which can be effective to enable the switching regulator to provide the current to the load more quickly.
