Error amplifier and DC-DC converter and the method thereof
The DC-DC converter of the present invention sets the soft start function in the error amplifier. With soft start added, the error amplifier's output voltage will follow the slowly ascending soft start voltage when the DC-DC converter is enabled. Then the soft start looses control over the error amplifier when the soft start voltage exceeds the steady state value of the error amplifier's output voltage. And meanwhile, the amplifier's input will take over the control. By doing so, the present invention significantly eradicates or reduces jitters caused by the output voltage of the error amplifier and the DC-DC converter.
