CONTROL CIRCUIT, DCDC CONVERTER, AND DRIVING METHOD |
摘要 |
A current generator circuit included in a triangle-wave generator circuit in a control circuit includes plural stages of current mirrors connected in parallel with each other. The plural stages of current mirrors are placed so that the sum of output currents output therefrom becomes an output current of the current generator circuit. A switching element that controls the on/off state of a current in accordance with the amount of load current of a DCDC converter is connected to each of the current mirrors.
