LED Driver IC Features

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.

Scalability and Flexbility—Lower R&D Throughput Time

The multi-channel LED driver ICs are highly scalable and flexible. With one boost IC, our solutions can be scaled from 2 channels to 12 channels with output powers between 30 W to 140 W. 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. adaptive driving beam (ADB), advanced front lighting (AFL), laser, etc. 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.

Automotive Quality Guaranteed

All of our multi-channel automotive LED drivers are housed in a very small HVQFVN32 pin package. They are specially designed to support the growing replacement of traditional automotive lighting solutions with high-brightness (HB) and intelligent LED solutions. The devices are fully automotive qualified, compliant with AEC-Q100 grade 1, with an ambient temperature operating a range of -40 to +125°C. The devices also deliver low electromagnetic emission (EME) and high electromagnetic immunity (EMI).

S32K-ISELED LED Lighting Solution

Engineered for next-generation smart LED lighting systems and based on the new ISELED technology which addresses calibration and communication issues in today’s LED lighting systems by moving the costly external processes for ensuring stable light parameters to embedded processing in the RGB LED itself.
