Abstract
Disclosed herein are a switching mode converter and a method for controlling thereof. The switching mode converter includes a switching element, a bootstrap capacitor, and a control unit. The switching element is connected between one side of a first semiconductor device, another side of the first semiconductor device is connected to a ground, and an input power. The bootstrap capacitor is configured such that one side of the bootstrap capacitor is connected to the one side of the first semiconductor device. The control unit controls the output current or output voltage of a common charge pump provided to the switching element and the bootstrap capacitor in order to control the charging state of the bootstrap capacitor and the gate voltage of the switching element.
