摘要: A near-zero cross-regulation (near-zero CR) single-inductor bipolar-output (SIBO) converter with an adaptive-energy correlation (AEC) control is proposed as a compact power management solution for driving cholesteric-LCD (Ch-LCD). The SIBO converter can provide a pair of positive and negative output voltages with only one external inductor for achieving the polarity reversion operation in Ch-LCD to obtain high-quality displays. The proposed AEC control decides energy distribution for bipolar outputs without any cross regulation through the embedded prediction function. The chip fabricated in a 0.25 mu m CMOS process demonstrates near-zero cross-regulation at bipolar outputs with 90% peak power conversion efficiency.
