Abstract
A power-on control circuit controlling a first output switch and a second output switch is provided. A detecting circuit detects a first voltage to generate a detection signal to a first node. A switching circuit receives the first voltage and a second voltage and transmits the first or second voltage to a second node according to the voltage level of the first node. A setting circuit generates a feedback signal to the first node according to a voltage level of the second node. When the first voltage reaches a first pre-determined value and the second voltage has not reached a second pre-determined value, the switching circuit transmits the second voltage to the second node. When the second voltage reaches the second pre-determined value, the switching circuit transmits the first voltage to the second node.
