| Abstract: | Based on the HHNEC 0.35 um BCD process,a dynamic slope compensation circuit applied to peak current mode boost converter is designed.The circuit can provide proper slope compensation with the variation of input and output,which avoids the defect of traditional slope compensation,such as small system load capacity and slow transient response.Verified by Cadence Spectre,this circuit can achieve the designing purposes. |
