Exciting New LED Driver from Diodes Incorporated
Diodes Incorporated (Nasdaq: DIOD) has recently made strides in the automotive lighting sector with the launch of its automotive-compliant LED driver, the AL8866Q. This innovative driver addresses the demanding needs of high-power LED lighting systems and supports a variety of topologies including buck, boost, buck-boost, and SEPIC.
Enhanced Functionality for Automotive Applications
The AL8866Q is ideal for an array of automotive applications ranging from daytime running lights to brake lights. Its wide input voltage range of 4.7V to 85V makes it versatile enough to cater to standard 12V, 24V, and 48V battery configurations. This flexibility allows lighting designers to streamline their operations by relying on a single versatile component.
Advanced Control Architecture
With a peak current-mode control architecture operating at 400kHz, the AL8866Q is designed to promote enhanced electromagnetic interference (EMI) performance by utilizing a spread spectrum frequency modulation technique. This approach not only adheres to the stringent CISPR 25 Class 5 standard but also ensures better operational stability in various environments.
Precision Dimming and Reliability
This LED driver excels in dimming capabilities, supporting both analog and PWM dimming functions through its DIM pin. It achieves a remarkable over 100:1 analog dimming range, offering 12% accuracy in output current, particularly beneficial for applications requiring precise brightness control. For PWM dimming, the driver supports frequencies from 0.1 to 1kHz, ensuring a broad dynamic range for smooth lighting adjustments.
Robust Safety Features
Safety and reliability are paramount in automotive applications, and the AL8866Q is designed with numerous protective features. Its soft-start function gently ramps up inductor and switch current, mitigating the risk of an output overvoltage situation. Additionally, it includes an open-drain fault output that alerts users to possible issues such as LED output overvoltage, open or short-circuit conditions, and thermal shutdown.
Available Packages and Pricing
This LED driver is offered in two compact package options: SO-8EP and U-DFN3030-10, both engineered to perform effectively in extreme temperature ranges from -40°C to +125°C. The pricing for these components starts at $0.50 and $0.48 for the AL8866QSP-13 (SO8-EP) and AL8866QFN-7 (U-DFN3030-10), respectively. Diodes also provides a standard compliance version of the driver for industrial uses.
