Here’s a look at these applications and related solutions. In addition, automotive applications demand special measures because of the extreme power-supply conditions that occur. Then there are the matters of driving LCD backlighting. However, driving LED strings and controlling brightness require much more sophisticated circuitry. For some simple applications, it’s just applying a forward bias voltage through a current-limiting resistor.
#LED DRIVER WITH BRIGHTNESS CONTROL HOW TO#
Perhaps the main challenge for designers is learning how to power the LEDs. The result has been increased adoption of LEDs in home, auto, and other applications. And their prices have decreased to an acceptable level. LEDs are now brighter and use less power than any other lighting source. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty LED. The devices also deliver low electromagnetic emission (EME) and high electromagnetic immunity (EMI).Light-emitting diodes have become the lighting source of choice for almost all illumination applications. The devices are fully automotive qualified, compliant with AEC-Q100 grade 1, with an ambient temperature operating a range of –40 to +125☌. They are specially designed to support the growing replacement of traditional automotive lighting solutions with high-brightness (HB) and intelligent LED solutions.

Automotive Quality GuaranteedĪll of our multi-channel automotive LED drivers are housed in a very small HVQFVN32 pin package. Together with the optimized, architecture, package and pinning, our solution reduces the R&D throughput time for both new product developments and future product upgrades. adaptive driving beam (ADB), advanced front lighting (AFL), laser, etc. Furthermore, via the SPI interface, the driver ICs are highly programmable, which empowers our solutions to be capable of driving all kinds of advanced lighting applications, e.g. With one boost IC, our solutions can be scaled from 2 channels to 12 channels with output powers between 30 W to 140 W. The multi-channel LED driver ICs are highly scalable and flexible. Scalability and Flexbility-Lower R&D Throughput Time Therefore the multi-channel LED driver ICs can achieve high output powers with minimum PCB area and without expensive thermal components. This enables the optimal thermal performance of the drivers under high current situations (>1.5 A per channel). Furthermore, the multi-channel buck ICs use an external power MOSFET for each channel. The high level of digital integration ensures a low external component count for maximum robustness and ease of design. Together, they provide a single platform architecture that has the capability to drive any configuration of LEDs and channels while keeping system cost down. The portfolio consists of two families - the multi-phase boost ASLx500 and multi-channel buck ASLx416 driver ICs. Our driver IC portfolio is designed to enable maximum design freedom with minimum cost in the initial design, mass production and future system updates. High-class automotive A-BCD mixed signal HV technology. They combine our deep understanding of LED performance with our Lighting applications-maintaining system flexibility, enabling design re-use and providing significant
