In a DC-DC converter, a controller is configured to provide control cycles subsequently. Each of the control cycles includes a first ON-period and a second ON-period subsequent to the first ON-period. One switching element is turned on, and another switching element is turned off the first ON-period. The one switching element is turned off, and the another switching element is turned on for the second ON-period. A controller is configured to determine lengths of the first and second ON-periods based on high-side and low-side voltages. The controller is configured to turn on the one switching element in an initial ON-duration in the first ON-period of a control cycle among the control cycles which is firstly provided. The initial ON-duration has a length shorter than the determined length of the first ON-period. The controller turns off the one and another switching elements in a duration in the first ON-period in the first control cycle other than the initial ON-duration. The controller is configured to turn on the one switching element and turn off the another switching element for the determined length of the first ON-period of each of one or more control cycles among the control cycles other than the first control cycle. The controller is configured to turn off the one switching element and turn on the another switching element for the determined length of the second ON-period of each of the control cycles.
