摘要: A switching regulator comprising a droop amplifier responsive to a reference voltage and a feedback voltage to generate a droop voltage. The droop amplifier includes a boost circuit configurable to increase a transconductance of the droop amplifier during an upward transition of the reference voltage. The switching regulator further includes a comparator responsive to the droop voltage and a current sense signal. The comparator is configured to initiate switching in the switching regulator.
