Abstract
A DC-DC converter includes a first switch connected between an input node and a switching node, a second switch connected between a reference node and the switching node, a capacitor having a first terminal connected to one of the input node and the reference node, a transformer including a primary coil connected between the switching node and a second terminal of the capacitor, and a secondary coil, a rectification smoothing circuit that rectifies and smooths a voltage of the secondary coil, and a drive circuit. The drive circuit alternately turns on the first and second switches, such that a dead time during which both the first and second switches are turned off has a length corresponding to a time period during which a voltage of the switching node is transitioning from a low state to a high state or the high state to the low state.
