Description	Common Anode Capable High Brightness LED Driver
Datasheet	LM3434-NationalSemiconductor.pdf

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

include thermal shutdown, VCC under-voltage lockout, and logic level shutdown mode. The LM3434 is available in a low profile LLP-24 package. Features.
Operating input voltage range of -9V to -30V w. r. t. LED anode.
Control inputs are referenced to the LED anode.
Output current greater than 6A.
Greater than 30kHz PWM frequency capable.
Negative output voltage capability allows LED anode to be tied directly to chassis for maximum heat sink efficacy.
No output capacito.
