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 AG (FSE: IFX / OTCQX: IFNNY) 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. Maximum LED system efficiency with LITIX Power Flex TLD5541-1QV The TLD5541-1QV is a first available member of the newmulti-topology DC/DC controller family LITIX Power Flex. 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. The TLD5541-1QV features seamless buck-boost regulation and fast dynamic load jump behavior. Therefore, it enables cost-optimized LED headlamps with complete protection and diagnosis features. Just one TLD5541-1QV can drive two and more separately switched LED loads in one string, with up to 55 V string voltage. The LED current accuracy is specified with +/- 3 percent. The TLD5541-1QV with built-in protection features and SPI interface offers both analog and digital (PWM)

footprint, easier development and simple worldwide integration with the ability to receive multiple different digital, as well as analog radio standards and to switch between them via software. Centralized infotainment head units, distributed radio/audio systems, as well as smart antenna solutions are perfectly supported by this new one-chip family.” Availability: Engineering samples are available for our lead NXP radio designs are in 19 of the top 20 tier-1 automotive offerings delivering more than 500 million car radios in the past 10 years.
