    Abstract: Average inductor current control with open- and closed-loop regulation. One example is a method of operating an LED module, the method comprising: controlling, by an on-off controller, a high-side FET and a low-side FET to create a plurality of charge modes and discharge modes of an inductor coupled to an LED of the LED module, each charge mode ends at a peak current indicated by a signal applied to a peak-current input of the on-off controller; driving, by an open-loop regulator, a zenith-current signal to the peak-current input, the open-loop regulator calculates the zenith-current signal for each charge mode without using a feedback signal indicative of current through the LED; and driving, by a closed-loop regulator, a peak-current signal to the peak-current input, the closed-loop regulator calculates the peak-current signal for each charge mode based on the feedback signal indicative of current through the LED.
