Patent ID: 7723972

Claim:
A system for reducing soft-start delay and providing soft recovery from a short circuit or brown out condition in a power converter, the system comprising: an error amplifier having a first input terminal and a second input terminal, the error amplifier receiving a feedback signal indicative of the output voltage of the power system at its first input terminal, the error amplifier receiving a soft-start reference voltage at its second input terminal, the error amplifier operable to compare the feedback signal against the soft-start reference voltage to generate a control signal for regulating an output voltage of the power converter; circuitry coupled to the first input terminal of the error amplifier for establishing a range around the feedback signal and forcing the soft-start reference voltage to stay within the range around the feedback signal; and circuitry coupled to the second input terminal of the error amplifier for pre-charging a soft-start capacitor associated with the soft-start reference voltage, thereby reducing soft-start delay.
