Abstract: This paper presents a hybrid-switched-capacitor-resonant (HSCR) light-emitting diode (LED) driver based on a stackable switched-capacitor (SC) converter IC rated for 15–20-W applications. Bulky transformers have been replaced with an SC ladder to perform high-efficiency voltage… read more here.
