Design of LED driver ICs for high-performance miniaturized lighting systems

Abstract

This paper presents several high-performance LED driver ICs for AC-powered miniaturized lighting systems. With the help of presented techniques, the value of bulky inductors can be effectively reduced for the switching-converter-based LED drivers, while the flicker reduction and visible-light communication can be integrated into the compact inductor-less drivers. In addition, a hybrid driver with improved efficiency is achieved by combing two conventional driving approaches.
