AC-DC LED Driver IC
Get the right power control for your LED Driver
Infineon's AC to DC LED driver ICs and controller ICs deliver excellent power quality and high efficiency for LED lighting applications supporting dimming levels down to 0.1%. The high integration of advanced functions saves external components and minimizes system cost. The wide variety of features and functions gives the option to choose the best fitting part for the application and desired topology. Infineon’s range of AC to DC drivers offer optimal efficiency while providing fast and stable reactions to dynamic load changes.
The ICL88xx family of single-stage flyback AC-DC LED controllers ICs for constant voltage output is tailored for cost-efficient LED lighting applications. The mixed signal control ICs have an optimal price/performance ratio with excellent power factor, THD, low EMI, and optimum efficiency at high light quality. Infineon’s AC-DC constant voltage LED controller ICs, such as ICL8800, includes all basic family features, whereas the advanced ICL8810, and the fully-featured ICL8820, include additional features that enable smart lighting such as low stand-by power or jitter for emergency lighting.
In the ICL5102 (Infineon’s highly integrated PFC (power factor correction) + HB (half-bridge) combo controller), the integration of PFC and HB into a single controller enables reduction of external components and optimizes performance by harmonized operation of the two stages. Compared to level-shifter technology, the integrated coreless transformer featuring galvanic isolation not only further reduces the loss at high operation frequency, but also enhances the capability of handling huge negative voltages.
Low variation in the output voltage and current allows for best-in-class THD and high-power factor as well as a greater ability to withstand AC line perturbations. The multi-mode operation of PFC converter provides excellent efficiency over the whole load range. The wide input voltage range up to 480VAC in ICL5102HV enables global high power designs with just one device.
The XDP™ high performance digital power control AC-DC LED Driver ICs for LED lighting address today’s challenges such as smart or connected lighting, meeting demanding LED driver requirements with a unique set of features. The broad portfolio ranges from single stage high power factor controllers that are primary/secondary side regulated (e.g. XDPL8219) to dual stage flyback combo controllers with integrated PFC (such as XDPL8221 a multi-control ac-dc constant current led driver ic / constant voltage led driver IC/ limited power led driver IC). Integrated start-up cell, high voltage capabilities, ultra-low stand by power consumption, UART interface, and parameter setting via .dp interface board all enable numerous designs by just one platform design.
Infineon’s extensive portfolio of AC-DC LED driver (integrated) circuits includes solutions for a range of LED lighting applications as well as power supplies LED drivers, horticultural lighting, and also industrial and residential lighting applications. With high performance and efficiency and increased design flexibility, Infineon’s AC-DC LED driver ICs are the ideal choice for flicker-free LED drivers for indoor and outdoor lighting systems as well as multi-mode LED drivers for connected lighting systems.
