On January 16, 2017, Germany Munich -led car headlights enable energy saving, support new headlights such as matrix beams and laser high beams. Infineon Technology Co., Ltd. (FSE: IFX / OTCQX: IFNNY) provides strong support for automotive lighting technology, launching high-power LED drivers designed for car headlights, which are 2 products for Litix Power Flex and Litix Power series. These devices provide a flexible DC / DC driver for LED systems with up to 50 W or even higher. The device's application is flexible, including a voltage of up to 55 V, a light string composed of a large number of medium power LEDs, or a lighting device consisting of a small amount of up to 3 A and a higher LED.
Litix Power Flex TLD5541-1QV and Litix Power TLD5190QV These two LED drivers are ideal for high-power and large current LED applications. These include car headlights, lasers and LED headlights. In addition, they are used as high-efficiency power supplies, and they are also ideal for using battery powered LED applications. Furthermore, they also help to design cost savings, all LED car headlights, including design can be installed in a small space, such as the economical all LED headlights on the motorcycle car.
LitiX Power Flex TL5541-1QV helps maximize LED system efficiency
TLD5541-1QV is the first product of the new multi-topological DC / DC controller series Litix Power Flex. Synchronous H Bridge DC / DC Controller is ideal for driving various high-power LED devices, and the highest system efficiency exceeds 92%. This can improve system reliability and improve thermal performance, and reduce the PCB size. Thanks to the switching frequency optimization, the adjustable range is expanded, and TLD5541-1QV helps reduce EMC radiation, satisfying strict EMC requirements such as CISPR 25 Class 5.
TLD5541-1QV has seamless buck-boost adjustment and fast dynamic load hopping performance. Therefore, it can rely on perfect protection and diagnostic functions to help achieve cost savings LED headlight design. A TLD5541-1QV can drive two or more LED loads that use separate switches on the string of up to 55 V. The current accuracy specification of the LED reaches +/- 3%.
TLD5541-1QV is equipped with built-in protection and SPI interfaces that enable simulation and digital (PWM) dimming. The switching frequency can be adjusted within the range of 200 kHz to 700 kHz. The adjustable soft start function limits the current peak and the voltage overshoot at startup.
Litix Power TLD5190QV helps reduce LED system costs
The Litix Power Series DC / DC Converter and Controller facing the medium and high power application, including LED daylighting lights and LED low beams and high beams. The new member of the product series TLD5190QV is a synchronous H-bridge DC / DC controller with a function similar to TLD5541-1qv. It does not have a SPI interface, especially suitable for LED control electronic devices that need to be equipped with a microcontroller, while more easily implementation. In addition, it also provides integrated protection functions, analog and digital (PWM) dimming, supporting adjustable switching frequencies from 200 kHz to 700 kHz.
illustrate:
LitixTM Power Flex and LitixTM LED drivers are designed for car headlights. They provide a flexible DC / DC drive solution for the design power up to 50 W or even higher LED systems, which can be used to drive the voltage up to 55 V, a light string composed of a large number of medium power LEDs, or consisting of a small amount of LEDs. 3 A and even higher lighting devices.
