摘要： A DC-DC converter with transient control. The DC-DC converter includes a power switching circuit, a current to voltage converter, a PI circuit 403, a voltage to current converter 404 and a logic and control circuit 405. The DC-DC converter obtains the transient information of a current flowing through the power switching circuit, to slow down the variation of the output voltage, so as to eliminate the overshot issue.
