Abstract
A switching voltage regulator circuit includes, in part, a latch, a pair of switches, a sensing circuit, an amplifier, a digital control block, and a comparator. The switches are responsive to the latch, and the sensing circuit is responsive to a current flowing through the switch that is on. The amplifier is responsive to a reference voltage signal and a voltage feedback signal to generate a first intermediate voltage signal. The digital control block receives the reference voltage signal and the voltage feedback signal and generates a second intermediate voltage signal operative to cause the difference between the voltage feedback signal and the reference voltage signal to be less than a predefined value. The first and second intermediate voltages define a threshold value. The comparator is adapted to receive the output of the sensing circuit and the threshold value and to change the state of the latch in response.
