IC LED driver ASL series

constant-current

Our ASLxxxx series of LED drivers includes versatile, application-specific, constant-current, high-brightness LED (HB-LED) driver ICs. They provide a fully integrated solution for automotive LED lighting applications—maintaining system flexibility, enabling design re-use and providing significant scalability in a low-cost solution. They combine our deep understanding of LED performance with our high-class automotive A-BCD mixed signal HV technology. Optimum Architecture—Lower System Cost Our driver IC portfolio is designed to enable maximum design freedom with minimum cost in the initial design, mass production and future system updates. The portfolio consists of two families - the multi-phase boost ASLx500 and multi-channel buck ASLx416 driver ICs. Together, they provide a single platform architecture that has the capability to drive any configuration of LEDs and channels while keeping system cost down. Optimum Integration—Lower Space The high level of digital integration ensures a low external component count for maximum robustness and ease of design. Furthermore, the multi-channel buck ICs use an external power MOSFET for each channel. This enables the optimal thermal performance of the drivers under high current situations (>1.5 A per channel). Therefore the multi-channel LED driver ICs can achieve high output powers with minimum PCB area and without expensive thermal components.
