P‐43: LED Backlight Driver Implemented by Single‐stage Linear Regulation Control (LRC) Technique for High Efficiency and Low Cost

Abstract: LCD panel with the LED backlight can be controlled by the proposed linear regulation control (LRC) technique for high efficiency and low cost. The LRC technique removes most of the external passive components, which include inductor, E-cap, freewheel diode, and blocking diode. Due to single-stage operation without two-stage power consumption, small volume and high efficiency can be simultaneously ensured. Furthermore, the PLL function can guarantee the line voltage and current to be in phase so as to realize t… Show more
