Abstract:

In this paper, a large load output integrated converter is designed based on the technology of DC-DC converter. For the problem of the harmonic oscillation in the peak current mode control, the slope compensation circuit is introduced. An adaptive slope compensation circuit is designed to improve the load capacity. In order to eliminate the slope compensation effect on the load capacity, a dynamic clamping circuit is introduced, which improves the chip output current capability effectively.

Key words: DC DC converter, slope compensation, active clamp
