Abstract

Regulator circuitry configured to manage power supply ripple using an adaptive loop gain that offers ripple rejection performance related to the ripple magnitude for a negative closed loop of the regulator circuitry. The power supply regulator circuitry of this disclosure includes an error amplifier in the closed loop and an adaptive loop gain circuitry. The adaptive loop gain circuit removes a DC component of the sensed output and feeds the sensed output, including the output ripple, to peak detector circuitry to obtain a Vpeak signal. The Vpeak signal output from the peak detector circuitry is a continuous signal that tracks the wave peak. The circuit arrangement multiplies the output of the error amplifier by the signal Vpeak resulting in improved power supply ripple rejection as the ripple amplitude increases. To avoid control signal with zero value during times that the peak-to-peak value of the sensed voltage.
