Inductorless (Charge Pump) LED Drivers
Analog Devices has a very broad line of LED drivers for backlighting applications. They are configured as either inductorless white LED drivers (for LEDs in parallel) or inductor-based white LED drivers (for LEDs in series). Topologies include boost regulator LED drivers, buck regulator LED drivers, buck-boost LED drivers, and more. Regardless of topology, these LED drivers offer the highest efficiency, lowest noise, and the smallest footprints. Other features include integrated Schottky diodes, accurate LED current matching, and multiple output capability.
