摘要：
In one embodiment, an LED control circuit is configured control a current through an LED responsively to a value that is proportional to a control signal for values of the control signal that are less than a threshold value of the control signal and to control the current to a value that is proportional to the threshold value for values of the control signal that are greater than the threshold value.
