Abstract: System and method for a burst-mode switching voltage regulator with good stability and small output voltage ripple. A preferred embodiment comprises a current sense circuit coupled to a power switch in the burst-mode switching voltage regulator to sense a current flowing through the power switch. The sensed current can then be used (in conjunction with a feedback control signal that is based on the output voltage and is generated at the output of the burst-mode switching generator) to control the operation of the power switch to regulate the output voltage of the burst-mode switching voltage regulator. This enables the use of an output regulator with a small equivalent series resistance to minimize voltage ripple while providing good operational stability and fast transient response.
