Abstract:
According to an embodiment, a current detection circuit includes a transistor, an operational amplifier, and a transistor. In the transistor, the source and the gate are coupled to the source and the gate of a transistor which is provided on a high side of a drive circuit. The operational amplifier amplifies a potential difference between a drain voltage of the transistor and a drain voltage of the transistor. The transistor is provided over a current path through which a current flowing to the transistor flows, and which has the gate to which an output voltage of the operational amplifier is supplied. A value of the current flowing through the transistor is detected based on a value of the current flowing through the transistor.

Claim (Index 1):
A DCDC converter comprising:\n a drive circuit; a current detection circuit configured to detect a value of a current flowing through a first drive transistor; a first comparator configured to compare a detection result of the current detection circuit and a reference voltage; and a pulse signal generation unit configured to generate a pulse signal of a duty ratio in accordance with a comparison result of the first comparator, wherein the drive circuit has\n a second drive transistor provided on a low side, and being controlled to be turned ON/OFF based on a dead time existing therebetween complementarily with the first drive transistor in accordance with a pulse signal, and \n an inductor provided between the first and second drive transistors and the external output terminal.
