Abstract
A regulated switching power converter generates a converter output having first and second regulated output values under corresponding operating conditions. The converter output transitions between the first and second output values in response to transition of a trigger signal in a transition window between first and second trigger values. A transition step function is based on transition amplitude, transition interval and number of steps, the transition amplitude being a difference between the first and second regulated output values, and the transition interval being a difference between the first and second trigger values. The transition step function generates a step-like transition signal based on values of the trigger signal between the first and second trigger values. During operation in the transition window, the step-like transition signal is included in the regulation reference value to generate a step-like transition of the converter output between the first and second regulated output values.
