I am a little confused with the use of VRM in this forum. I thought it stood for Voltage Regulation Module for the CPU power supply yet I see applied to the MOSFET switches used in the circuit. Could we have a definition please.
I have seen a request to define the MOSFET terminals. Control is via the Gate, the input signal is applied across the gate and source. The Source and Drain pass the main switching current. Depending on circuit configuration the Drain will be the supply and the Source the output, or this is reversed with a supply polarity change. For N channel MOSFETs the Drain is positive. For P channel MOSFETs the Drain is negative.
Hope this is clear.
