In one example, a method includes receiving a voltage value and comparing the voltage value to a reference voltage value to determine a delta voltage value. The method may also include determining a reference current value based on the delta voltage value. The method may also include receiving a current value and comparing the current value to the reference current value to determine a delta current value. The method may also include determining a threshold value based on the delta current value, where the threshold value is used to define a control signal that controls a power converter.

Digital controller with nested loops for switched mode power converter

In accordance with an embodiment, a controller for a switched mode power supply includes an average current comparator that determines whether an average current within the switched mode power supply is below a current threshold, and a switch signal generation circuit coupled to the average current comparator having switch signal outputs configured to be coupled to a switching circuit of the switched mode power supply. The switch signal generation circuit produces a first switching pattern in a first mode of operation and produces a second switching pattern a second mode of operation. When the average current comparator determines that the average current is below the current threshold, the switch signal generation circuit is operated in a first mode, and when the average current comparator determines that the average current is not below the current threshold, the switch signal generation circuit is operated in a second mode.
