Claim:
1. A system, comprising: an electronic chip having a current control input configured to receive a reference signal, and an output coupled to a power input of a device, the electronic chip configured to provide power to the device based on the reference signal input to the current control input; and a wave shape generator having an output coupled to the current control input of the electronic chip to provide the generated reference signal, the wave shape generator configured to generate the reference signal comprising a wave with a wave shape having a slope, a first portion of the wave above a minimum threshold to turn on the electronic chip, and a second portion of the wave below the minimum threshold to turn off the electronic chip, wherein at least one of the slope, the first portion, or the second portion is predetermined based on a desired intensity level for the device, and wherein the electronic chip, to control a level of power delivered to the device, cycles between an on state and an off state in response to the first portion of the wave and the second portion of the wave.
