Embodiments of the invention provide a pulsed-output constant voltage LED driver comprising a PDM stage configured to provide power to an LED load by supplying energy at either a first or second predetermined voltage during each of a plurality of segments of a predetermined time period, wherein the number of segments during which the first voltage is supplied is correlated with the power provided to the LED, and wherein the positions within the time period of the segments during which the first voltage is applied are random. Embodiments of the invention provide a method of supplying power to an LED load using a pulsed-output constant voltage LED driver, the method comprising: varying a number of pulses provided by the pulsed-output constant voltage LED driver over a fixed period of time such that the number of pulses determines the power level provided to the LED load, wherein varying the number of pulses allows for modulation in a light output of the LED load, and wherein the temporal position of the pulses in the fixed period of time is random.
