Abstract

This paper presents a high integrated dual-side dual-output (DSDO) switched-capacitor (SC) regulator with only two flying capacitors. Generally, a dual-phase voltage doubler and an inverter are used to supply positive and negative voltage for TFT-LCD gate drivers, respectively. Four flying capacitors, eight pin-outs, and sixteen power switches are necessary for their operations in the driver integrated chip (IC). The proposed DSDO SC regulator combines both dual-phase voltage doubler and inverter converter into one channel through the use of time multiplexing technique at the cost of little performance degradation. As a result, it not only diminishes the number of flying capacitor from four to two but also removes four IC pin-outs for low cost and compact size. Beside, sixteen necessary power switches are reduced to twelve for decreasing about 27% silicon area.
