意法半导体的单片式降压开关稳压器具有高达55 V的输入电压和高达4 A的输出电流，并且具有高开关频率。它们为驱动高亮度LED提供了简单、高效且经济的解决方案。该系列器件还具有专用调光电路。
3A LED driver with integrated DC-DC converter for automotive applications
The new ALED6000 is a single-chip automotive LED driver with integrated DC/DC converter designed to source up to 3 A on a single strip LED and to operate with a wide input-voltage range of 4.5V to 61V, which makes it the ideal choice for automotive systems.
Housed in a HTSSOP16 Package, the ALED600 is suitable for exterior lighting such as daytime running lights, headlights, rear lights, stop lights, and turn signals, as well as interior lighting.
Evaluation board is also available to help developers consolidate their designs STEVAL-ILL089V1.
LED5000 - 宽范围亮度控制与高设计灵活性
LED5000为单片式降压开关调节器，专为驱动长线LED设计，输入电压范围为5.5到48 V，输出电流最大3A，反馈电压极低（200 mV)。
它内嵌有高性能PWM电路用以调节LED亮度。具有最高的设计灵活性，可实现降压-升压（正或负）或浮动升压等其它拓扑
