... VID pins. The slew rate is always fixed by the soft-start capacitor. Core Regulator Output The ISL6271A core regulator is a synchronous buck regulator that employs an Intersil proprietary switch-mode topology known as Synthetic Ripple Regulation (SRR). The SRR architecture is a derivative of the conventional hysteretic-mode regulator without the inherent noise sensitivities and dependence on output capacitance ESR ...
