− | '''Voltage Regulator Module''' ('''VRM''') is an [[electronic circuit]] that [[voltage regulator|regulates]] and down steps [[voltage]] from its input (e.g., system [[power rail]]) to its output (e.g., integrated circuits). In the context of a typical computer, the VRM converts the 12/5/3.3 [[volt|V]] [[direct current|DC]] power rail that comes from the [[power supply unit]] into the much lower [[operating voltage]] of the [[integrated circuit]] (e.g. 0.8 V, 1 V, 1.2 V). VRMs are typically implemented as a [[switching regulator]] such as a [[buck converter]] due to their efficiency. | + | '''Voltage Regulator Module''' ('''VRM''') is an [[electronic circuit]] that [[voltage regulator|regulates]] and down steps [[voltage]] from its input (e.g., system [[power rail]]) to its output (e.g., integrated circuits) while stepping up [[current]].
