Detailed explanation of new dimming scheme based on LT3743 LED driver

/a>, from DLP Projectorhigh current in ledto high power laserdiodeand many more. For example: In high end video projectors, high power LEDs” title=”LED”>LED” title=”LED”>LED” title=”LED”>LED are used to produce colored lighting. RGB LEDs in these projectors require Precise Dimming Control for Accurate Color Mixing – In this case, more control can be provided beyond simple PWM dimming. Typically, to achieve the wide dynamic range required in color mixing, LEDs The driver must be able to quickly switch between two completely different regulated peak current states and superimpose PWM dimming without any damage. The LT3743 meets these stringent accuracy and speed requirements.
