IR's Family of CHiL Digital PWM Controllers and Integrated PowIRstage® Solutions Provide Optimized End-to-End Solutions with PMBusTM for Next-Generation Computing Platforms
EL SEGUNDO, Calif. --(Business Wire)--
International Rectifier, IR® (NYSE: IRF), a world leader in
power management technology, today introduced its latest generation of
highly versatile, PMBus™ enabled, CHiL digital PWM controllers and
integrated PowIRstage® solutions that significantly improve
efficiency and reduce board space and component count in a variety of
mid-range to high-end server, desktop and computing applications.
IR's new digital controllers meet Intel (News - Alert) VR12 and VR12.5 specifications,
and support multiphase designs from 1 to 8 phases operating 1 to 2
loops. These digital controllers can be used in combination with a
choice of seven new PowIRstage® products to deliver an
optimized high-performance end-to-end multiphase solution for CPU and
DDR memory applications.
These latest generation CHiL controllers offer enhanced features over
the previous generation including significant expansion in the PMBus™
command set, substantial reduction in quiescent current to enable higher
peak efficiency, min/max telemetry recording and an improved high-speed
phase balance algorithm.
"Our latest generation CHiL digital controller family and PowIRstage®
solutions offer a complete optimized, full-featured, high-performance
end-to-end solution satisfying the challenging requirements of
leading-edge next-generation CPU and DDR memory designs for servers,
high-end motherboards and other computing systems. These new solutions
incorporate our latest silicon technologies to boost in-circuit
efficiences and offer a substantial upgrade in system-level telemetry
and reporting, fault protection and PMBus™ capability," said Carl Smith,
Marketing Director, IR's Enterprise Power Business Unit.
IR's latest PowIRstage® solutions integrate a high
performance driver, control and synchronous MOSFETs with accurate,
temperature compensated, on-chip current sense reporting and provide
cycle-by-cycle over-current protection to self-protect against harsh
circuit conditions such as inductor saturation events. Temperature
sensing, reporting and over-temperature protection are also available in
addition to a fault-flag output. These PowIRstage® devices
are offered in 6x6mm PQFN packages, rated at 40A, 50A and 60A with
over-molded and exposed top options available providing flexibility to
achieve optimal thermal design.

IR offers dedicated demo boards and fully documented reference designs.
These CHiL digital power solutions are fully supported by IR's real-time
GUI for design and development, and hardware interface tools to
communicate and program the CHiL devices.
Pricing for the controller range from US $3.81 each for the IR3584 to US
$4.13 each for the IR3580 in 1,000-unit quantities. Pricing for the
PowIRstage® devices range from US $3.19 each for the IR3557
to US $4.25 each for the IR3579 in 1,000-unit quantities. Prices are
subject to change.
