Boost DC-DC Converter With Fast Reference Tracking (FRT) and Charge-Recycling (CR) Techniques for High-Efficiency and Low-Cost LED Driver

An RGB LED driver with the fast reference tracking (FRT) and charge-recycling (CR) techniques is proposed to implement a high-efficiency and low-cost RGB backlight module in color sequential notebook computers' display. The proposed LED driver composed of an asynchronous 1.5 MHz DC/DC boost con...
