Abstract: Provided is an LED driver including an amplifier configured to receive a negative voltage input signal and produce a positive voltage output signal in response thereto. Also included is a microcontroller configured for sensing a value of the positive voltage output signal. The microcontroller (i) enters a programming mode when the value exceeds a threshold and (ii) produces an output current responsive to the value.

Abstract: Provided is a light emitting diode (LED) driver. The LED driver includes a microcontroller for setting a level of an output current of the driver. The driver is configured to receive a prefix as an input, the prefix instructing the microcontroller to enter a programming mode. The microcontroller is responsive to a level signal representative of the level of the output current during the programming mode.
