Abstract:
An electronic system includes controller to control a switching power converter to provide power to a load. To control the amount of power provided to the load, in at least one embodiment, the controller senses a current value representing a current in the switching power converter and detects when the current value reaches a target peak value. However, due to delays in the controller and/or the switching power converter, the detected target peak value will not be the actual current peak value generated by the switching power converter. In at least one embodiment, the controller adjusts the detected target peak value with a post-detection delay compensation factor to generate a delay compensated current value that more accurately represents an actual peak current value associated with the current in the switching power converter.
