This document discloses, among other things, apparatus and methods for dimmer control. In an apparatus example, a circuit can include an input configured to receive a control signal, a controller configured to modulate a pulse width of a pulse train using the control signal when the controller is enabled, an output configured to provide the pulse train to a driver, and first and second current limit detectors configured to receive load current information of the driver and to terminate an active pulse of the controller when a value of the load current information exceeds a threshold. |
