摘要： A method for controlling a switching voltage regulator that includes generating a feedback voltage that is proportional to the output voltage of the voltage regulator; generating a voltage proportional to the duty-cycle of the inductor charging and discharging phases as a function of the difference between the feedback voltage and a reference voltage; and adding a dominate pole and two zeros to the function used to generate the voltage proportional to the duty-cycle of the inductor charging and discharging phases.

摘要： A reverse current comparator for use in switching regulators includes a differential stage configured to encode the difference in voltage between an N and a P input. The differential stage feeds one or more gain stages. At least one of the gain stages includes one or more hysteresis devices. When the voltage of the N input exceeds the voltage of the P input by a predetermined margin, the hysteresis device causes the regulator to enter a triggered state in which it outputs a non-zero output voltage. Subsequent changes to the N and P inputs do not change the regulator output until a RESET input is asserted and which point the regulator enters a reset state and is ready to be triggered.

摘要： A switching regulator that practices the current invention includes a high-side switch M1 connected between an input voltage and a node Lx. A low-side switch is connected between the node Lx and ground. An inductor L is connected between Lx and an output node (VOUT). A filtering capacitor connects VOUT to ground. The switching regulator has two distinct operational phases. During the first operational phase, the high-side switch is OFF and the low-side switch is ON. During the second operational phase, the high-side switch is ON and the low-side switch acts as a current source. During transitions between the second and first operational phases, the low-side switch is controlled to momentarily decrease the regulated drain-to-source current.
