Akros Offers First Integrated, 2kV-Isolated, Quad-Output Power SoC

The AS1454 Integrates GreenEdge Isolation Technology on Silicon to Deliver a 92%
Efficient, Space-Saving and Cost-Effective Device for Isolated DC-DC Power
Applications
SUNNYVALE, Calif.--(Business Wire)--
Akros Silicon Inc. introduces an isolated quad-output digital power SoC that
sets a new integration benchmark for the isolated DC-DCs that are used in a wide
range of industrial, datacom, automotive, medical, residential gateway, display
and other distributed power applications. Built around Akros` field-proven and
patented GreenEdge digital isolation technology, the AS1454 eliminates the need
for low-speed, bulky opto-couplers and integrates the functionality of up to
eight separate ICs used in current implementations. This leads to a substantial
reduction in design footprint and bill-of-material costs. The AS1454`s built-in
cross-isolation DC-DC timing management and digital power control delivers 92%
DC-DC efficiency with excellent light-load efficiency management for
energy-efficient, green-power applications. The result is a power SoC that
delivers cost and energy savings-all while simplifying system designs with
digital power and electromagnetic compatibility (EMC) management features.

The AS1454 integrates a wide input range (9V-72V) isolated primary converter, a
2kV isolation barrier, a high-current-capable buck or boost PWM controller, and
two 2A buck regulators into a single device. Its wide-input voltage range allows
it to be used in 12VDC/24VDC/24VAC distributed power applications in industrial,
building management, analog surveillance camera and automotive systems, as well
as 48V distributed power applications in telecom, datacom, industrial and
medical equipment requiring a 36V-72V input voltage range. It offers selectable
spread-spectrum clocking on all pulse-width modulators (PWM) to reduce
power-supply spectral noise by more than 15dB to lower the EMI signature of the
switch-mode power supplies and ease system design for EMC compliance.

"With world-wide focus on energy saving initiatives, power subsystems play an
increasingly value-added role in overall system design," said Amit Gattani,
Network Power Business Unit Director for Akros Silicon. "The AS14x4 product
family allows our customers to address energy efficiency and lower cost
requirements of next-generation equipment, while reducing system level design
complexity and development costs. With the AS1454 platform solution, our
customers can leverage Akros` leadership in silicon to deliver cutting-edge
products even under challenging budgets and cost targets."

The AS14x4 product family consists of the AS1454, AS1444, AS1434 and AS1424
devices that cover the gamut of system power and feature requirements. The
AS1454/34 are I2C-capable with advanced system diagnostics and programmability
features. AS14x4 products are available in footprint-compatible, 64-pin 9x9 QFN,
Reduction of Hazardous Substance (RoHS)-compliant packages. Device pricing is
available upon request. Contact a local manufacturing representative and order
