ABSTRACT:
A switching regulator provided according to an aspect of the present invention contains uses one or more error samples from prior iterations, in addition to an error sample of the present iteration, to determine the correction for the present iteration. Due to the use of multiple samples, a switching regulator may provide a regulated signal which is at least substantially constant even in the presence of line/load variations. A controller determining the correction can be implemented either in analog or digital domain.
