  • LED driver circuit and method
    Patent number: 9420653
    Abstract: An LED driver circuit and a method for driving the LED driver circuit. In accordance with an embodiment the LED driver circuit includes a voltage follower circuit and a calibration circuit coupled to the voltage follower circuit. First and second currents may be injected into the node and a current is sunk from the node. In accordance with another embodiment, the LED driver circuit asserts a non-zero voltage across the light emitting diode in a first phase of a drive cycle and asserts a fixed non-zero current in the light emitting diode in a second phase of the drive cycle.
