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.
