We see from your search that you're looking for information on the term "VRM",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release MOSFET and diode on one chip boost efficiency from
Vishay Siliconix, which we summarised at the time by saying "Benefits result from the low forward voltage drop and reverse recovery charge of integrated Schottky diode and the reduced PCB parasitic inductance from both devices on a single
chip".
Several months prior to that,
we featured the news release Top speed placement set for Nuremberg launch from
Universal Instruments: "The Genesis GC-120Q is billed as the world's fastest quad-beam machine at 120,000 components per hour".
In February 2007, we covered the news from Contax
- take a look at Universal partnership is exclusive for Contax
which says: "Production automation system specialist Contax has signed an exclusive partnership agreement with Universal Instruments, one of the world's largest surface mount suppliers".
Take a look also at the news release from ON Semiconductor, Top-10 award for PWM controller chip,
as well as MOSFETs help maximise power densities from International Rectifier,
and Platform tops flip-chip machine poll from Universal Instruments.
