New synchronous
rectification ICs for simplicity
and efficiency in SMPS
applications
Infineon Technologies AG (FSE:
IFX / OTCQX: IFNNY) released the
IR1161L and IR11688S secondary
synchronous rectification (SSR)
family of Controller ICs to complete
Infineon’s product offerings for
SMPS applications.
The IR1161L and IR11688S SSR
ICs meet the new 2016 standards
set by the U.S. Department of
Energy and the “European Code
of Conduct for Energy Efficiency in
Data Centre” which demand a 1 to
3 percent efficiency improvement
over previous requirements. Taking
2 percent saving as an average for
new adapters, US adult notebook
users alone can save 525 GWh per
year – which is enough to power
New York City for at least 40 days.
Together with Infineon’s best in
class energy saving OptiMOS™
and StrongIRFET™ MOSFETs, this
family of SSR ICs provides a simple
solution for SMPS while improving
the overall efficiency. The IR1161L
is targeted for flyback SMPS in
chargers and adapters while the
IR11688S is targeted for LLC SMPS
in televisions, desktops, silver boxes
and micro-servers.
Both, the IR1161L and IR11688S
offer 200 V direct sensing which
eliminates the need for external
voltage dividers. The family also
features
programmable
MOT
(minimum on time) ensuring reliable
operation from no-load to full-load.
The low quiescent current capability
meets the standby requirements of
the new 2016 efficiency standard in
the industry.
Availability
Volume production of the IR1161L
and IR11688S has started. More
information about the new SSR
family is available at www.infineon.

Snapdragon 821 builds
on 820 processor success
Since thebeginningof theyear, when
the first Qualcomm Snapdragon
820 powered smartphones were
announced, the 820 processor
has been a leader in the mobile
industry with over 115 premium
smartphone and tablet device
deployments, supporting the latest
in cutting-edge mobile applications,
and helping create more immersive
user experiences while also being
deployed in new and innovative
ways, like supporting safer driving
and navigation in cars.
One of the main reasons the
820 processor has been so
successful in so many designs is
because it introduced multiple new
technologies, all tightly integrated
and power optimized, designed to
bring user experience innovation to
the mobile industry.
But the innovation doesn’t stop
there.
This week, Qualcomm Technologies
is announcing a follow-up to
the successfulSnapdragon 820
processor: the Snapdragon 821.
Building on the technology
leadership introduced with the
Snapdragon 820platform, the 821 is
engineered to deliver faster speed,
improved power savings, and
greater application performance,
ensuring 821 powered devices keep
pace with the growing performance
demands of users to deliver the
unmatched user experiences the
Snapdragon 800 tier is known for.
The Snapdragon 821 is engineered
to deliver a 10% performance
increase over the 820 with the
Qualcomm Kryo quad-core CPU,
reaching speeds up to 2.4GHz. Why
would you introduce something to
replace what many consider the best
mobile processor available today?
Simple, we’re not. Rather than
replace the Snapdragon 820, the
821 is designed to complement and
extend the competitive strengths of
our Snapdragon 800 lineup.
The Snapdragon 820 introduced
a number of highly optimized and
custom-designed core technologies
and established an early and clear
leadership position in premium tier
mobile computing. Consider, for
example, the X12 LTE modem. It
