SUNNYVALE, Calif. – July 30, 2009 – 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 AS14×4 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 AS14×4 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. AS14×4 products are available in footprint-compatible, 64-pin 9×9 QFN, Reduction of Hazardous Substance (RoHS)-compliant packages. Device pricing is available upon request.
