Zusammenfassung:A digital control circuit is provided for use with a switch-mode power converter that receives an input signal at a first input node and a control signal at a second input node, and that provides an output signal at a first output node and a current signal at a second output node. The digital control circuit generates a programmable current reference signal based on a difference between the output signal and a voltage reference signal, calculates a time instant when the current signal substantially equals the programmable reference current signal, and generates the control signal based on the calculated time instant.
