A DC-DC converter includes a bootstrap circuit including a capacitor which is configured to be charged when a low-side switch is an on-state, and being configured to pull up an on-drive voltage of the high-side switch by a charged voltage of the capacitor, a control circuit configured to perform switching control of the high-side switch and the low-side switch, and a predetermined-time trigger circuit configured to cause an output to be active for a predetermined time, when a break signal for instructing switching control of the high-side switch and the low-side switch to be halted is inactive. The control circuit performs switching control to turn the high-side switch off and the low-side switch on, when the output of the predetermined-time trigger circuit is active.
