基于自适应二次斜坡补偿的高效峰值电流模式Buck DC-DC
A wide-range high-efficiency peak-current-mode Buck DC-DC converter based on adaptive quadratic slope compensation
摘要
Abstract
This paper presents a high-efficiency peak current-mode(PCM)Buck DC-DC converter utilizing adaptive quadratic slope compensation.The proposed design generates tailored adaptive slope voltages across wide ranges of input voltage,output voltage,load current,and switching frequency,resulting in excellent transient performance.Fabricated in a 55 nm BCD process,the chip occupies a compact core area of only 0.186 mm2.It supports an input voltage range of 3.7~5.0 V,an output voltage range of 1.5~3.5 V,a maximum load current of 1.00 A,and a switching frequency configurable from 1.0 MHz to 4.0 MHz.The converter achieves a peak efficiency of 96.0%,maintains efficiency above 93.0%at 1.00 A output current,and delivers over 90.0%efficiency across the load range from 0.03 A to 1.00 A.Post-layout simulation results confirm that the proposed compensation technique exhibits strong adaptability under varied application configurations.关键词
