Sunnyvale, Calif.Akros Silicon Inc. has introduced a 2kV-isolated, quad-output digital power SoC that can be used in a wide range of industrial, datacom, automotive, medical, residential gateway, display and other distributed power applications.
Built around Akros' 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.
According to Akros, the AS1454's built-in cross-isolation DC-DC timing management and digital power control delivers 92% DC-DC efficiency with optimum light-load efficiency management for energy-efficient, green-power applications.
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.
The AS14x4 product family consists of the AS1454, AS1444, AS1434 and AS1424 devices. The AS1454/34 are I²C-capable with advanced system diagnostics and programmability features. AS14x4 products are available in footprint-compatible, 64-pin 9×9 QFN, Reduction of Hazardous Substance (RoHS)-compliant packages.
Pricing: Budgetary 1ku pricing is $4.19 for the AS1454 higher-power software version device and $3.59 for the AS1424 for the lower-power hardware version device.
