Infineon enables compact and cost-effective LED front light applications with LITIX LED driver family

LEDs in automotive front lighting enable energy savings, new light designs and applications such as matrix beam and laser high-beam. Supporting the progress in automotive lighting Infineon Technologies launched high-power LED drivers specifically designed for automotive front lights. The drivers are available within the new LITIX Power Flex series and the LITIX Power series. They address flexible DC/DC driver solutions supporting LED systems of up to 50 W and even above. Application setups can vary: many medium-power LEDs with string voltages of up to 55 V or few LEDs with high currents of up to 3 A and more.

Both LED drivers, the LITIX Power Flex TLD5541-1QV and the LITIX Power TLD5190QV, are well-suited for high-power and high-current LED applications. These include for example front lighting, laser and LED headlamps. They also suit high-efficiency supplies for LED applications working on battery voltage. Furthermore, they allow cost-optimized full-LED front light applications for cars and even motorcycles with their space limitations in the handlebar’s headlamp.

The synchronous H-bridge DC/DC controller is ideal for driving all high-power LED configurations with maximum system efficiency of well above 92 percent. This results in higher reliability and improved thermal behavior and reduced PCB size. Thanks to its optimized spread spectrum switching frequency, the TLD5541-1QV helps reduce EMC emissions to fulfill challenging EMC requirements like CISPR 25 class 5.
