An integrated LED controller drives and reads a passive dimmer and controls a power circuit for the LED. The integrated LED controller detects changes in the position of the passive dimmer and causes the power circuit to brighten or dim the LED accordingly. These functions are normally performed by multiple discrete components. However, the integrated LED controller is implemented as a single integrated circuit, thus reducing the size and cost of the LED dimming system. The integrated LED controller can also include a unified timing controller that coordinates the timing of multiple functions within the controller in a manner that reduces the noise sensitivity of the controller.

A flyback converter is provided that dynamically adjusts a drain threshold voltage for a current cycle of a synchronous rectifier switch transistor based upon operating conditions in a previous cycle of the synchronous rectifier switch transistor. A differential amplifier drives a gate voltage of the synchronous rectifier switch transistor during an on-time of the current cycle so that a drain voltage of the synchronous rectifier switch transistor equals the drain threshold voltage during a regulated portion of the current cycle.
