Abstract
A switching regulator with improved load regulation is discussed. The switching regulator increases an on time length of a first power switch if the switching regulator operates at discontinuous current mode and a current flowing through the second power switch crosses a zero reference, until the first power switch is turned on again; and the switching regulator maintains the on time length of the first power switch during other time period.
