Patent ID: 7795754

Claim:
A slope control device capable of predicting uniform-current-sharing level, for a power module applying with a droop method, and said power module having an original output voltage-current slope, and comprising a sample resistor, and said slope control device comprising: a transconductor circuit, for generating a detection current based on a detection voltage on said sample resistor while said output current of said power module passing said sample resistor, and for outputting the information of said detection current; a slope adjusting circuit, for adjusting said original slope into a modified slope based on said information of said detection current; and an incremental output voltage circuit; wherein while said output current is lower than said preset current value and said output voltage decreases to an output voltage minimum value due to the increasing of said output current and said modified slope, said incremental output voltage circuit pulls up said output voltage based on said information to ensure that said output current is increased to approximate a preset current value.
