Abstract
A switching regulator includes a power stage, an output capacitor, a first reference voltage generator, a comparator, a constant-time trigger, an error amplifier, and an operator. The power stage includes a first switch, a second switch, and an output inductor. The comparator is coupled to the output inductor and the operator for receiving an output voltage and a compensation reference voltage. The error amplifier is coupled to the output inductor and the reference voltage generator. The constant-time trigger is coupled to the comparator and the power stage. The operator is coupled to the reference voltage generator and the error amplifier.
