AC-DC LED Driver IC

Infineon's AC-DC LED driver ICs deliver excellent power quality and high efficiency for LED lighting applications supporting dimming levels down to 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.

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 and 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 480V AC in ICL5102HV enables global high power designs with just one device.

The XDP™ high performance digital power control 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 primary/secondary side regulated (e.g. XDPL8219) to dual stage flyback combo controllers with integrated PFC (like XDPL8221). Integrated start-up cell, high voltage capabilities, ultra low stand by power consumption, UART interface and parameter setting via .dp interface board enable numerous designs by just one platform design.
