Abstract
An object of the disclosure is to provide cancelling of the output voltage deviation in a switching converter, caused by Equivalent Series Inductance (ESL) of the output capacitor, using switching node information. A further object of the disclosure is to eliminate a step-like voltage deviation in the equalized output, further eliminating the need to increase the Panic comparator offset reference, and eliminating the need to reduce the bandwidth of the pulse-width modulation control loop. Still further, another object of the disclosure is to merge some of the new components depending on the circuit topology. Still further, another object of the disclosure is to implement the new components with the same silicon as the control block, for matching the output voltage ripple and the cancelling signal control.
