Fast response detection method of buck converter and its suit under current mode

摘要

According to the ideal embodiment example of the invention, by detecting the super suit and the lower suit, the fast response current mode hysterical frequency converter and its action method include:In a buck converter using current mode hysterical control (current mode lag control).The difference between feedback voltage and output voltage is used to detect overshoot and undershoot.By adjusting the output voltage using the detected signal,It can improve the load transition response characteristics.
