Stop and tail LED driver

tony777

I have a analog dimming signal (from hide-side switch) to single stop/tail LED light.

10% PWM (tail) and 100% (Stop).

I need to control this signal two separate LEDs array (Stop and tail).

Does TI have any LED driver to do this?

I attach an oscilloscope screen of PWM signal.

Hi Tony,

How about the current and voltage rating for this application?

The voltage of my application is 12V. (My device must be compatible with the motorcycle power system)

I need to supply 4 red LED strip. LED max Forward Voltage is 2.5V. Current through LEDs equals 20-30 mA.

You can consider the TPS9261X series, but they don't have analog dimming feature. But you can use supply dimming method in this case.
