Abstract:
1. A system corrected programmable integrated circuit, which is applied to a power supply, comprising a comparator unit which includes an external feedback voltage input end and a reference voltage input end, wherein the external feedback voltage input allows for inputting a feedback voltage and the reference voltage input end allows for inputting a reference voltage continuously, such that when the feedback voltage is equal to the reference voltage, the comparator unit will send out a control signal; a digital output unit which receives the control signal and allows for outputting the reference voltage continuously, such that when the digital output unit receives the control signal, the reference voltage will stop being outputted and the current reference voltage is recorded as a programming voltage which is outputted, as well; and a programming unit which receives the programming voltage, such that when the programming unit receives the programming voltage, the programming voltage is programmed and transmitted to the reference voltage input end.
