Abstract
An output feedback control circuit includes, for example, a first amplifier configured to generate a first error signal commensurate with a difference between an output voltage, which is fed to a load, or a feedback voltage commensurate therewith and a reference voltage, a second amplifier configured to be faster than the first amplifier and to generate a second error signal commensurate with a difference between the output voltage or the feedback voltage and the first error signal (or the reference voltage), a calculator configured to superimpose a remote sense signal, which is derived from a grounded terminal of the load, on the reference voltage, which is fed to the first amplifier, and a capacitor connected between an application terminal for the first error signal and an application terminal for the remote sense signal.
