National’s PowerWise LED drivers such as the LM34xx/LM340x/LM35xx families offer a maximum power-to-performance ratio, which means you get more features than standard incandescent and fluorescent lighting solutions at a fraction of the wattage. Using National’s PowerWise LED drivers, results in energy-efficient solutions that reduce power consumption.
The LM3404/04HV are monolithic switching regulators designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, they contain a high-side N-channel MOSFET switch with a current limit of 1.5 A (typical) for step-down (Buck) regulators.
