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 - Wide brightness control and high design flexibility
The LED5000 is a monolithic buck switching regulator specifically designed to drive long LED strings with an input voltage range from 5.5 to 48 V, an output current up to 3A and a very low feedback voltage (200 mV).
It embeds high-performance PWM circuitry for LED brightness. The highest design flexibility is given by the possibility to implement other topologies such as buck-boost (positive or negative) or floating boost
