Integrated two-stage PFC + LLC/LCC resonant half-bridge controller for LED drivers in DSO-19 package

ICL5102HV control IC forLED driversoffers 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 ICL5102in a DSO-16 package.
