Abstract
A controller for a switching mode power converter is configured to drive a switching element to selectively connect a supply to a primary side winding of a transformer to generate a regulated voltage, current, or power at a secondary side winding of the transformer. The controller is configured to, for each switching cycle, select a peak current value from a plurality of peak current values calculated to drive an oscillating voltage at the switching element to correspond to a voltage valley and in response to determining a voltage valley is occurring at the oscillating voltage at the switching element, output an enabling signal to cause the switching element to generate a channel electrically connecting the supply to the primary side winding until current at the switching element is not less than the selected peak current value.
