LED Drivers for Lighting
We offer a growing portfolio of LED drivers used for automotive lighting applications. With unique process technology and applications expertise, our highly integrated LED driver ICs with on-chip FETs and diverse control options provide flexibility and functionality in a small solution footprint. Allegro’s LED driver portfolio covers a wide variety of topologies, channel counts, output currents and feature sets to help customers optimize their solutions.
Fast/controlled startup allows customers to minimize time-to-light, which is important for safety considerations. Wide range dimming control facilitates optical design including theater up/down dimming as well as bi-level light output such as for automotive stop/tail or DRL/position lamps.
We also provide proven EMC reference designs tested in our in-house EMC laboratory to ensure successful and rapid EMC compliance. Plus, our field is well trained and ready to support your projects at the local level.
