ICL5102HV control IC for LED drivers offers a unique one-package solution for lighting applications up to 350W, supporting LLC/LCC topology. It is particularly designed to deliver best performance of total harmonic distortions (THD) and power factor (PF). Compared to level-shifter technology, the integrated coreless transformer not only further reduces the loss at high operation frequency, but also enhances the capability of handling huge negative voltage (-600V on HSGND). Reduce the number of external components to optimize form factor and reduce bill of material (BOM) with the integrated two-stage combination controller (PFC + LLC/LCC) for lighting applications. Simplify your design and scale down time-to-market.For lower AC voltage, Infineon also offers ICL5102 in a DSO-16 package.

With ICL5102 Infineon offers a highly integrated combo controller IC with a universal input of 70V to 325V, which allows manufactures to realize global designs, keeping cost for product variety and stock low. Highest efficiency of up to 94 percent by resonant topology, a THD factor less than 3.5 percent and a high power factor of more than 0.95 allow for more lumen output and less thermal load, enabling cost effective designs and keeping cost for LEDs and heat sink low. Thanks to the high integration, there is no need for additional expensive components in PFC and LLC stage, reducing the overall BOM cost. In addition integrated protection features complement the ICL5102 features.

The IRS25411S is a high voltage, high frequency buck control ic for constant LED current regulation. The IRS25411S incorporates a continuous mode time-delayed hysteretic buck regulator to directly control the average load current, using an accurate on-chip bandgap voltage reference. The application is inherently protected against short circuit conditions, with the ability to easily add open-circuit protection. An internal high-side bootstrap circuit drives the buck switching element at high frequencies. A low-side driver is also provided for sychronous rectifier designs. All functions are relaized with a simple 8-pin SOIC package.
