Claim Text:
1. The switching regulator comprising: a droop amplifier, responsive to a reference voltage and a feedback voltage, to generate a droop voltage; the droop amplifier comprising a boost circuit configurable to increase a transconductance of the droop amplifier during an upward transition of the reference voltage; and a comparator responsive to the droop voltage and a current sense signal, the comparator being configured to initiate switching in the switching regulator and wherein the boost circuit comprises an auxiliary resistor coupled to a switch, the switch being controlled to activate the boost circuit during the upward transition of the reference voltage, wherein the boost circuit is activated based on an output of an up/down counter wherein the up/down counter receives a target DAC code and compares the target DAC code against the current DAC code such that during the upward transition of the reference voltage the boost circuit is activated.
