Abstract
This paper presents a LED driver based on a new Hybrid-Switched Capacitor Converter (H-SCC) operating in the MHz range, which uses the internal pulsed nodes of a Dickson converter and an LC output network to provide output current dimming. The converter is implemented using 5V integrated capacitors and switches in a 0.18μm bulk CMOS technology. The experimental results show that the proposed LED driver has a power density of 122mW/mm2 and an efficiency of 79%, and only needs a small 40nH inductor.
