LM3434 Datasheet (Texas Instruments) - Common Anode Capable High Brightness LED Driver

LM3434, Common Anode Capable High Brightness LED Driver

The LM3434 is an adaptive constant on-time DC/DC buck (step-down) constant current controller (a true current source).

The LM3434 provides a constant current for illuminating high power LEDs.

The output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced cha
