ABSTRACT:
The present disclosure has been worked out to provide a buffer circuit and a control method thereof capable of controlling the timing at which the output switching element is changed from an OFF state to an ON state, and preventing the output characteristic from becoming unstable. The buffer circuit includes: a driving portion20driving output switching elements M1and M2; a detecting portion30detecting that the voltage values of control terminals of the output switching elements M1and M2have exceeded the threshold voltage value; an auxiliary driving portion40being connected to the driving portion20and changing driving capability of the output switching elements M1and M2in accordance with the result of detection by the detecting portion30.
