The new IRP6VRM1 offers the power supply designer
a complete turnkey solution for DC/DC converters required
to power next-generation microprocessors. A synchronous
buck regulator topology operating at 200kHz is employed
and achieves excellent efficiency with very fast load response
and tight output voltage regulation.
The new FETKY? D 2 Pak is used in the synchronous
recirculation circuitry to reduce board space and assembly
costs while actually improving circuit efficiency through

reduced stray inductance. Complete performance
characterization along with a detailed schematic,
bill-of-materials, PCB layout and modeling are offered to
reduce the customer’s design time and effort.
Purpose
This is a production-ready design. It has been thoroughly
tested for performance against the Intel P6 power
specification, and evaluated for manufacturability by a
high volume manufacturer.
This design will not be manufactured by International
Rectifier. Its purpose is to simplify the design and
qualification process for our customers.
Web Site
This design may be downloaded in two formats at IR’s
web site (http://www.irf.com). One is PDF format for
on screen viewing or printing, the other is in native
format.
Floppy Disk
The design is also available on floppy disk. As on our web
site, the floppy version contains two formats, PDF and
native format.
Demo Boards
Completed boards are available free to IR customers, and
at a reasonable charge to others.
