Abstract
A power supply apparatus, comprising: a driver connected to a power source voltage and configured to perform an ON/OFF operation of power supply to a load; a digital control circuit configured to perform an ON/OFF control of the driver; and an oscillator configured to output an oscillator signal for performing the ON/OFF control of the driver every constant period. The digital control circuit operates in a normal control mode in which the output operation of the oscillator signal by the oscillator and the ON/OFF operation of the driver are continuously activated, or in a low power control mode in which the output operation of the oscillator signal by the oscillator and the ON/OFF operation of the driver are intermittently activated.
