About

Multi-channel LED drivers for full automotive headlamp systems

Full LED headlights contain ECUs with multiple channels driving all the light functions of the headlamp. Therefore, they integrate power stages as well as communication interfaces and microcontrollers. Infineon offers dedicated solutions for supply and communication as well as for LED control.

Robust and efficient range of boost and buck-boost control ICs

LITIX™ Power / Power Flex: our boost and buck-boost control ICs have been proven as robust solutions for compact and efficient automotive DC-DC converters for many years. Our synchronous buck and buck-boost controllers enable high-performance converters for high LED currents.

Design guide for automotive front light high/low beam solutions

If you are starting from scratch, see our reference design LEDFRONTHBLB_REF. The design guide describes the implementation of an automotive front light high beam/low beam combination in detail. It uses the flexible multi-topology DC-DC controller TLD5099EP of the LITIX™ Power family in the current-controlled buck-boost SEPIC configuration.
