Desktop Computer Motherboard Meeting The Components
The main components of a voltage regulator circuit are the already mentioned chokes
(which can be manufactured using two materials, iron or ferrite), transistors and
electrolytic capacitors (good motherboards will provide solid capacitors, which are better).
The transistors used on the voltage regulator circuit are manufactured under a technology
called MOSFET (Metal-Oxide Semiconductor Field Effect Transistor) and many people call
them simply “MOSFET” (some motherboards, in particular the ones from MSI based on
"DrMOS" technology, use integrated circuits instead of transistors). Some motherboards
come with a passive heatsink on top of these transistors to cool them down, which is a
desirable feature. There are other very important components present on this circuit,
especially integrated circuits. You will always find an integrated circuit called “PWM
controller” and in good designs a tiny one called “MOSFET driver.” We will explain what
they do later.
