1. A soft-start circuit for power-up, comprising:
a reference value generation circuit, which is configured to output a reference value, which increases slowly, during a start-up process for power-up;
a protection threshold generation circuit, which is configured to output a protection threshold, which increases slowly, during the start-up process for power-up;
a control circuit, which is configured to control an output voltage to increase slowly along with the reference value based on the reference value, during the start-up process for power-up, and to limit an output current based on the protection threshold to limit the output voltage, during the start-up process for power-up.
