A power supply apparatus includes a switching transistor, a transistor control circuit, and a reference voltage generator. The switching transistor performs a switching operation for converting an input source voltage to an output power voltage according to a control signal. The transistor control circuit generates the control signal based on a reference voltage and a feedback voltage associated with the output power voltage. The reference voltage generator generates the reference voltage, increases the reference voltage in a phased manner to increase the output power voltage in a phased manner to a desired value, and decreases the reference voltage to decrease the output power voltage. A power supply method is also described.
