About

How does Infineon’s portfolio support LED lighting solutions?

We at Infineon have been focusing on LED drivers and connected and smart Lighting for many years. With our products and solutions, we are supporting high light and power quality in LED drivers as well as high efficiency of significantly above 90%. In the first step, the focus of the market has been on energy savings by just replacing incumbent light sources with LEDs. But due to further increase in energy cost and pressure on carbon footprint reduction, the efficiency of the LED drivers and the usage of presence detectors based on reliable radar technology are becoming more mainstream.

Whatever your need, Infineon has you covered with our portfolio of LED driver ICs that support a platform approach for LED drivers in commercial and industrial lighting as well as indoor and outdoor  LED lighting. A comprehensive portfolio of high-voltage MOSFETs and low-voltage MOSFETs, benchmark for linear- and switch-mode LED driver ICs, microcontrollers with dedicated peripherals for smart lighting system design and solutions, with high-efficiency power conversion, and dimming technologies as well as easy-to-use wireless communication and sensor solutions for presence detection.

Which LED driver solution fits your power level?

LED drivers are used to provide a constant current to LED light engines for commercial indoor lighting, street lighting, and horticultural lighting. For the power conversion in LED drivers, numerous topologies are deployed by different companies. For power levels below 100 W, single-stage power factor correction (PFC) combined with flyback in the primary stage, and DC-DC buck in the secondary stage have become common. For power levels above 100 W, PFC combined with half-bridge is mainly used, while LCC is the dominating topology.

For two-stage LED driving, we recommend primary constant voltage output, followed by a DC-DC buck, which enables benefits with regards to dimming, efficiency, cost, and scalability. The power range can be scaled by deploying either a single-stage flyback with constant voltage output for up to 100 W or a two-stage LLC with constant voltage output for above 100 W up to multiple hundred watts.

At Infineon, we offer a broad variety of primary side AC-DC and secondary side DC-DC boards dedicated to LED lighting. Depending on your requirements, you can select and test the suitable AC-DC stage and the best fitting DC-DC stage.
