摘要 提出了一种应用于电流型DC-DC转换器的自适应斜坡补偿电路.在分析斜坡补偿原理的基础上,提出了一种动态的斜坡补偿方法.该方法利用跨导线性环电路对补偿电流信号进行叠加,无需外加引脚引入输出电压,从而减小了芯片封装尺寸,以较少的电路使引入的斜坡补偿对系统带载能力和瞬态响应的负面影响减至最小.此电路采用UMCBCD工艺,在升压型DC-DC转换器2V转换8V的条件下,带载能力达到300mA,负载调整率为6.7mV/A. An adaptive slope compensation circuit used in current mode DC-DC converters is presented. After analyzing the theory of slope compensation,a dynamic slope compensation is proposed,which uses a translinear loop circuit for the operation of compensation current signal without the additional output voltage pin, saving package and die size on the chip. This slope compensation circuit can minimize the negative impact to load capacity and the transient response of the system. The circuit is designed with UMC BCD technology. When the input is 2V and the output is 8V,the load capacity of the boost DC-DC converter is 300mA and the load regu- lation is 6. 7mV/A.
