Abstract
A controller for controlling a DC-DC converter in a discontinuous conduction mode (DCM) includes an output module configured to provide a switch control signal to the DC-DC converter having an on-time and a switching frequency. The controller includes an on-time-control-module configured to receive a first compensation signal based on the output voltage of the DC-DC converter; and set the on-time of the switch control signal based on the first compensation signal. The controller also includes a frequency-control-module configured to receive a second compensation signal, wherein the second compensation signal is based on the output voltage of the DC-DC converter, and regulate the second compensation signal to a target range by setting the switching frequency of the switch control signal to one of a plurality of pre-defined discrete switching frequencies.
