LED Driver ICs

AC-DC LED driver ICs are ideal for LED drivers and luminaires. 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. This is why Infineon’s LED drivers have a deep dimming performance without flicker. The high level of integration simplifies designs by reducing the need for external components. Besides a broad analog LED controller IC portfolio, Infineon’s XDP™ LED Lighting portfolio of digital power technology supports easy designs and simplifies logistics handling, hence saving effort and cost.

DC-DC switch-mode driver ICs represent a good option for dual-stage professional lighting systems. Infineon offers a broad portfolio of highly integrated DC-DC LED driver ICs that support currents from up to 1.5A. The benefit of these LED drivers is that efficiency can be as high as 98% across a wide variety of operating conditions. They offer a fast, stable, and efficient regulation with a high light quality because of high current precision.

High-performance power management LED driver ICs and microcontrollers are made for intelligent lighting systems. Infineon offers the industry’s most comprehensive LED lighting IC portfolio for linking the real with the digital world – comprising an unparalleled range of hardware, software, and security solutions for the connected age. 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 for efficiency and demanding industrial applications.

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

LITIX™ are tailor-made LED driver ICs for automotive LED applications. Infineon’s LITIX™ is the best solution to benefit from the advantages of LEDs providing full protection to your automotive LED lighting applications. There will be no more overstress caused by e.g. voltage spikes or overtemperature because the LED protects itself against overstress. This feature, and many more, make Infineon’s LITIX™ suitable to be used inside a car with harsh automotive conditions.

Infineon’s BCR linear regulators are the perfect fit for LED strip light applications in industrial and automotive areas. This represents the lowest-cost solution that requires an ultra-low external part count and 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 new-generation BCR430U and BCR431U linear drivers feature an extra-low voltage drop and a smart temperature controlling circuit.

PROFET™ switches are ideally suited for advanced high-side LED lighting IC applications and are Infineon’s solution for power switch ICs. 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 switch 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.
