Abstract:
A method and apparatus comprises regulating, by a modulator of a LED controller, a plurality of current sinks to operate in a linear region of a current-to-voltage curve which is associated with a constant value of resistance, wherein each current sink is coupled to each of a plurality of LED strings, receiving, by the modulator, information of first current flowing through each of a plurality of LED strings, processing, by a control logic coupled to the modulator, the information of the first current, and based on the processed information of the first current, providing, by the control logic, at least two choices of information of second current that is to be flown through each respective LED string.

Claim (Index 1):
A lighting controller, comprising:\n transistors, each having first and second terminals and a control terminal; a current sensing device coupled to the second terminal of each of the transistors, the current sensing device configured to generate feedback signals, each representing a pulse width modulation (PWM) current conducted by each of the transistors; a modulation circuit coupled to the current sensing device, the modulation circuit configured to:\n receive the feedback signals and a dropout voltage of each of the transistors; and \n generate a regulation signal to the control terminal of a selected one of the transistors when the respective dropout voltage is greater than a predetermined threshold, the regulation signal configured to reduce a duty cycle and increase an amplitude of the PWM current conducted by the selected one of the transistors.
