Abstract
This paper presents a high efficient constant-current LED driver. It consists of a 1㎒ synchronous boost DC-DC converter and constant current control circuit. The proposed circuit is verified by using HSPICE with 0.35㎛ standard CMOS parameters. The proposed circuit has a simple structure. It can also simplify the PCB level design, by removing the external current sensing resistors.
