Design and Implementation of an Adaptive Slope Compensation Circuit
-
Abstract
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 regulation is 6.7mV/A.-
