Integrated two-stage PFC + LLC/LCC resonant half-bridge controller for LED drivers in DSO-19 package ICL5102HV control IC for LED drivers offers a unique one-package solution for lighting applications up to 350W, supporting LLC/LCC topology. It is designed to deliver best performance of total harmonic distortions (THD) and power factor (PF). Compared to level-shifter technology, the integrated coreless transformer reduces the loss at high operation frequency, and also enhances the capability of handling huge negative voltage (-600V on HSGND).
