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 9):
A circuit for regulating a pulse width modulation (PWM) current conducted by a transistor coupled to a series of light emitting devices, the circuit comprising:\n a window comparator coupled to receive a dropout voltage of the transistor, and configured to detect an event in which the dropout voltage exceeds a predetermined threshold; and a control logic coupled to receive a feedback signal representing the PWM current, the control logic configured to generate a regulation signal to reduce a duty cycle of the PWM current and increase an amplitude of the PWM current based on the event detected by the window comparator.
