Abstract:
A soft start circuit includes an error amplifier for generating a control signal according to an input voltage, a feedback voltage and a reference voltage, a feedback circuit for generating the feedback voltage according to an output voltage, an internal voltage source for generating a soft start voltage, and a sink circuit including a first transformation module for generating a first transformation current according to the soft start voltage, a second transformation module for generating a second transformation current according to the feedback voltage, a comparison module coupled to the first transformation module and the second transformation module for generating a comparison result according to the first transformation current and the second transformation current, and an output module coupled to the comparison module for generating a sink current according to the comparison result, so as to control the control signal.
