DC-DC converter, method for controlling DC-DC converter, and electronic device |
摘要 |
A DC-DC converter includes a switching element to generate a pulse waveform by repeatedly admitting and cutting off the input voltage, a fluctuation component restraining circuit to restrain a fluctuation component generated in superposition on the pulse waveform and having a shorter cycle than a cycle of the pulse waveform, and a control circuit to operate the fluctuation component restraining circuit when the input voltage is equal to or larger than a reference voltage.
