Provided is a mechanism for providing a light emitting diode (LED) lighting compatible dimmer. The mechanism includes a detector configured to detect changes in current received from rectified output power and a boost controller responsive to the detecting and providing an operating mode signal to a boost device in accordance therewith. The boost device provides power to a load based upon an operating mode signal including a constant current mode if a current change is detected or enters a power factor control (PFC) mode if the current change is not detected. |
