Power supply apparatus with soft-start and protection

A power supply apparatus with a protection mechanism, comprising:

• a power unit, generating a power voltage;
• a soft-start adjusting unit, coupled to the power unit, receiving the power voltage and a plurality of controlling signals, and transforming the power voltage to a soft-start current according to the controlling signals, so as to output the soft-start current to the voltage stabilizing unit or output or stop outputting the power voltage;
• an output end, coupled to the soft-start adjusting unit and suitable to output the soft-start current or the power voltage;
• a detecting unit, coupled to the output end, detecting a current state and/or a voltage state of the output end, so as to generate a detecting signal;
• and
• a controlling unit, coupled to the detecting unit and the soft-start adjusting unit, receiving the detecting signal, so as to generate the controlling signals.
