Lighting ICs

Infineon delivers innovative, high-performance lighting IC solutions with best-in-class technologies that can be used in a broad range of lighting applications. The type of LED drivers used in a lighting application has a significant impact on its overall performance. Therefore, you benefit in many ways from choosing Infineon’s products.

AC-DC LED driver ICs are ideal for replacement lamps, luminaires and LED drivers. Infineon's innovative multi-mode LED driver ICs deliver high efficiency, high power factor, and low harmonics to LED lighting applications. Dimming down to one percent light output has become mainstream for indoor lighting. That is why Infineon’s LED driver have a deep dimming performance without flicker. The high level of integration simplifies designs by reducing the need for external components. Beside a broad analog LED control IC portfolio, Infineon’s XDP™ LED lighting portfolio of digital power technology supports easy designs and simplifies logistics handling, hence saving effort and cost.

Infineon’s BCR linear regulators are the perfect fit for LED strip light applications in industrial and automotive, representing the lowest-cost solution that requires an ultralow external part count and very little PCB space. When there is the need to drive LED strings supplied by a DC voltage source, BCR linear LED driver ICs are the best choice. The BCR430U and BCR431U feature an extra-low voltage drop as well as a smart temperature controlling circuit.

DC-DC switch-mode driver ICs are suitable for dual-stage professional lighting systems. Infineon offers a broad portfolio of highly integrated DC-DC LED driver ICs that support currents from 150mA to 3A. That is why they are the ideal choice for high- and ultrahigh-power LEDs. The benefit of those is that the efficiency can be as high as 98 percent across a wide variety of operating conditions. Thanks to their high current precision, they offer a fast, stable and efficient regulation with a high light quality. The multi-topology high-power DC-DC LED driver IC with built-in protection features offers the most flexible dimming options.

High-performance power management ICs and microcontrollers are made for intelligent lighting systems. Infineon offers the industry’s most comprehensive portfolio for linking the real with the digital world – comprising an unparalleled range of hardware, software and security solutions. XMC1000 microcontrollers bring together the ARM® Cortex®-M0 core and market-proven and differentiating peripherals in a leading-edge 65nm manufacturing process. Infineon’s XMC™ 32-bit industrial microcontroller portfolio is designed to meet the efficiency requirements in demanding industrial applications.

Infineon’s extensive portfolio of leading-edge CoolMOS™ and OptiMOS™ power MOSFETs comprises an extremely well-established technology in LED driver applications. The revolutionary CoolMOS™ products offer a significant reduction of conduction-, switching- and driving losses, and enable high power density as well as efficiency for superior power conversion systems. The full range of OptiMOS™ and StrongIRFET™ power MOSFETs enables innovative, reliable, and high performing designs, addressing applications such as switch-mode power supplies (SMPS), battery-powered applications, motor control and drives, inverters, and computing.

Infineon’s LITIX™ devices are tailor-made LED driver ICs for automotive lighting IC applications. LITIX™ is the best solution to benefit from the advantages of LEDs providing full protection to your automotive lighting application. There will be no more overstress caused by e.g. voltage spikes or overtemperature, because the LED protects itself against overstress.

PROFET™ switches are ideally suited for advanced high-side lighting IC applications. PROFET™ stands for protected MOSFET and gathers all high-side switches, whether they are automotive qualified or designed for the needs of industrial applications. The well-established high-side industrial PROFET™ products were designed for targeting a variety of industrial applications which include all types of resistive, inductive, and capacitive loads. Due to their outstanding energy robustness, they are perfectly suitable for switching even higher inductive loads and driving relays.
