Abstract
A synchronous rectification DC/DC converter includes a first transistor and a second transistor including respective main electrodes connected to a common connection point, the first transistor and the second transistor being NMOS transistors, a control circuit configured to control switching of the first transistor and the second transistor in a complementary manner, a bootstrap circuit that includes a first capacitor charged with a current supplied from a high voltage potential terminal and is configured to raise a voltage potential of a control electrode of the first transistor to turn on the first transistor, and a charging stop circuit configured to stop the first capacitor from being charged from the high voltage potential terminal in a time period in which the first transistor and the second transistor are turned off simultaneously.
