Design of Peak Current Mode Synchronous Buck DC-DC Converter

Mao Fan, Shuzhuan He, Baoning Zhang


In this article, a design scheme of peak current mode synchronous buck DC-DC converter is proposed based on synchronous rectification technology. The specific design scheme of the DC-DC converter is described from the overall structure design of control circuit, key circuit design and slope compensation. At the same time, the whole circuit simulation analysis of the DC-DC converter shows that the DC-DC converter has high performance.
