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).
