LED Driver IC
Analog Devices has a very broad line of LED driver ICs for automotive, display backlighting, handheld, and general high-power lighting applications. They are configured as either inductorless (charge pump) or switching regulator-based LED drivers that support driving white LEDs in series, parallel or combination. Topologies include boost regulator, buck regulator, buck/boost, SEPIC topology LED drivers, and more. Regardless of topology, these ICs offer the highest efficiency, lowest noise, and the smallest footprints. Other features of our portfolio include integrated Schottky diodes, accurate LED current matching, and multiple output capability.
