Abstract

This paper introduces a design of slope compensation circuit for peak-current-mode boost DC-DC converter. The circuit is simple, and eliminates instability problem of the peak-current-mode system generated by double-loop control. And it avoided detrimental effects on account of improper compensation, such as slow transient response, low carrying capacity. It improves the stability of the switching power supply. The design is implemented base on the TSMC´s 0.35 μm CMOS process. The spectre simulation results show that, when the inductive current occurs disturbance, the system do not occur prolonged oscillation, can supply stable output voltage.
