Abstract

A bootstrap circuit unit of a DC-DC converter applies, to a drive unit, a voltage that is higher than that at a first connection point between switching elements in a first conversion operation, and applies, to the drive unit, a voltage that is higher than that at a second connection point between switching elements in a second conversion operation. A charge-pump circuit unit steps up an input voltage and applies the resulting voltage to the drive unit. The drive unit sets the voltage of a first drive signal and a second drive signal according to a voltage applied by the bootstrap circuit unit or a voltage applied by the charge-pump circuit unit. The charge-pump circuit unit determines the operation timing at which the charge-pump circuit unit is to apply the output voltage, based on the first and second voltage, and the first and second power supply unit charging signals.
