Abstract
A fast transient switching voltage regulator includes a reference signal generator to provide a reference in a feedback path to control switching. The reference signal generator is operative to incorporate a voltage offset into the reference signal timed with the control pulses used to control the switching. The voltage offset moves the reference signal out of the way of pulses introduced in the feedback path due to capacitance ESL in the output capacitor of the switching voltage regulator.
