During operation, the LED current can be controlled using the 1 wire digital interface (Easyscale™ protocol) through the CTRL pin. Uses range from 3W LED flashlights, to bicycle lights, to solar powered architectural lighting. Their high-efficiency and high-switching frequencies make them well suited to modern consumer equipment.Diodes' linear LED drivers provide a simple cost-effective solution to driving low-current, high-brightness LEDs.Licensed LED Partners Off-Line LED Drivers The default white LED current is set with the external sensor resistor Rset, and the feedback voltage is regulated to 200 mV, as shown in the Typical Application section. click site
Smart high-side drivers may be the answer. The boost converter runs at a 1.2 MHz fixed switching frequency with 1.2 A switch current limit and allows for the use of a high brightness LED in general lighting. Topologies include boost regulator LED drivers, buck regulator LED drivers, buck-boost LED drivers, SEPIC topology led drivers and more.Regardless of topology, these LED driver ICs offer the highest efficiency, lowest noise, Smart High-Side Drivers Help Meet Tough New Automotive Standards The automotive stop/start feature reduces emissions and saves gas but requires a different approach to power drivers. http://www.digikey.com/en/product-highlight/t/texas-instruments/tps61165-high-brightness-led-driver
