CHARLOTTE, N.C., March 16, 2015 /PRNewswire/ -- APEC –
Intersil Corporation (NASDAQ: ISIL), a leading provider of
innovative power management and precision analog solutions today
announced the industry's first 50A fully encapsulated digital DC/DC
PMBus power module. The ISL8272M is a complete step-down power
supply that delivers up to 50A of output current from industry
standard 12V or 5V input power rails, and four modules can be
combined to support up to 200A rails. It provides point-of load
conversions for advanced FPGAs, ASICs, processors and memory in
space-constrained and power-dense telecom and datacom applications.
The device is also well suited for high-end instrumentation,
industrial and medical equipment. Used in conjunction with
Intersil's PowerNavigator™ graphical user interface (GUI), the
ISL8272M simplifies system power conversion and configuration,
while speeding design time.
The complexity and performance of the latest FPGAs and
processors used in wired, wireless and cloud computing systems is
driving up the number of voltage rails. For example, some optical
transmission systems have as many as 60 power supplies on a single
board. This complexity requires a higher level of system
intelligence and advanced digital power management, including
telemetry and system monitoring, to ensure 99.999% uptime. There
are real economic impacts when a telecom system or a router goes
down. For example, online purchases from Internet retailers can be
lost during transmission, making uptime critical.
The ISL8272M's digital control technology provides precise
sequencing and system monitoring through the PMBus interface. The
innovative ChargeMode™ control architecture enables
compensation-free design that keeps the device stable regardless of
output capacitor changes due to temperature, variation or aging.
Competitive voltage-mode control power modules often require
designers to perform complex calculations, stability analysis and
build a compensation network using 4-5 discrete components. The
ISL8272M's ChargeMode control loop also provides a single clock
cycle fast transient response to output current load steps common
in FPGAs and DSPs processing power bursts.
"Cloud computing's high availability demands are requiring
systems to control and monitor every power rail to maximize
efficiency and reduce downtime," said Mark
Downing, senior vice president of Infrastructure and
Industrial Power Products at Intersil. "The highly integrated
ISL8272M offers our customers a higher current, intelligent digital
power module solution that monitors and controls power supply
voltages, currents, temperatures and fault status, while
dynamically optimizing system power efficiency on the fly."
The 50A ISL8272M relies on Intersil's proven, fourth generation
digital controller family and expands on the existing 25A ISL8270M
and 33A ISL8271M digital power modules, giving customers an easy
migration path to higher current power rails. Additionally,
Intersil's family of fully encapsulated power modules is compatible
with all industry pick and place equipment for full manufacturing
automation.

PowerNavigator GUI Simplifies Digital Power Designs
Intersil's PowerNavigator™ GUI software simplifies the
ISL8272M's setup and configuration, including all device parameters
and full telemetry. The tool makes it easy to change features and
functions of a digital power supply design without writing a single
line of code. To download the PowerNavigator GUI and watch a
tutorial video, please visit: www.intersil.com/powernavigator.
Pricing and Availability
The ISL8272M is available in a compact 18mm x 23mm x 7.5mm HDA
package, and priced at $50.75 USD in
1k quantities. Two evaluation boards are available to speed
time-to-market: the ISL8272MEVAL1Z 50A digital module evaluation
board priced at $83 USD, and the
ISL8272MEVAL2Z 150A evaluation board priced at $150 USD.
