Abstract
A feedback signal generating circuit may include a control voltage adjusting circuit outputting a feedback voltage by comparing a control voltage input from an external voltage source with a reference voltage and adjusting a ratio of control voltage drop, and an amplifying circuit generating a feedback signal by differentially amplifying the feedback voltage and a detection voltage associated with a current flowing in a load.
