Abstract

A single-inductor multiple positive- and negative-output (SIMPNO) converter provides a compact-size and high efficiency solution for electronic paper displays (EPDs) system. With the single inductor multiple output structure, an adaptive current control methodology with the proposed vector current control mode (VCCM) can wisely minimize the current tolerance to be smaller than 10 % between input and all outputs. Additionally, owing to the VCCM technique for adequate inductor current control, the cross regulation is smaller than 0.35 V/A. The test chip was fabricated by 0.25 μm BCD process with a peak value of 90 % at heavy loads.
