Spread Spectrum Frequency Modulation Reduces Automotive LED Driver EMI

The large number of electronics in an automobile must have reasonably low electromagnetic interference (EMI) in order to avoid disturbing the radio reception, GPS navigation tools, and other forms of communication and broadcast. Switch mode regulators are commonly used in this environment, and they have to be designed to mitigate their inherently noisy nature. This is not always easy, especially since the power and amount of electronics in a car is growing.

Linear Technology's LT®3795 breaks new ground in LED driving regulators, achieving high-power automotive LED driving conversion, robust short-circuit protection, and reduced EMI with the use of a triangle spread spectrum frequency modulation. The spread spectrum frequency modulation of the LED driver is specifically designed to work with the LED driver and prevent possible LED flicker when the LEDs are run at full power and while they are PWM dimmed for brightness control.
