Abstract:
A driver circuit that includes an input side including a power input circuit and an output side including a light emitting diode (LED) output current circuit. The output side of the driver circuit includes an output smoothing capacitor for controlling flicker percentage. A light emitting diode (LED) power supply circuit is present between the input side and the output side for controlling current from the AC power input circuit to the light emitting diode (LED) output current circuit. The LED power supply circuit includes at least two linear current regulators that are connected in parallel. The circuit also includes a controller circuit including a controller for signaling the light emitting diode (LED) power supply to control current to the light emitting diode (LED) output current circuit to provide a lighting characteristic.
