Abstract
The present disclosure provides sensing a peak current and estimating a turn-off time of a switch using the peak to perform a discontinuous current mode (DCM) operation. According to the present disclosure, the buck-boost DC/DC converter includes: a first control circuit configured to build up a current, input through an input node, in an inductor during a first time period of a switching period; a sensing circuit configured to sense a current input through the input node to generate a sampling value for estimating a duration of a second time period; and a second control circuit configured to receive the sampling value from the sensing circuit and to output the current built up in the inductor through an output side during the second time period estimated based on the sampling value.
