Abstract
A circuit and method for providing an improved current monitoring circuit for a switching regulator. A circuit providing switching regulation with an improved current monitor, comprising a pulse width modulation (PWM) controller configured to provide P- and N-drive signals, an output stage connected to said PWM controller and configured to provide switching, comprising a high-side and low-side transistor, driven by said P- and N-drive signals, respectively, a sense circuit configured to provide output current sensing from the output stage during a sampling period when the N-drive signal is active, and a sampling timing generator configured to provide a an n-sampling signal, nsample, to the sense circuit, wherein a start of the n-sampling signal is delayed by a first delay after the sampling period and the n-sampling signal is ended prior to an end of the sampling period by a second delay.
