Ferric Announces the Industry’s First Commercially Available Single Chip Power Converter with Integrated Magnetic Inductors.

The Fe1038D replaces traditional step-down buck converters and all necessary passive components with a single chip.

Ferric, Inc. announces today, the industry’s first and only commercially available single-chip power converter with integrated magnetic thin-film power inductors.  The Fe1038D is a synchronous 3A step-down converter suitable for powering high performance digital, analog and mixed signal loads, such as microprocessor IO, applications processors and FPGAs. The Fe1038D is a complete power converter on a chip, including all necessary passive components, which allows for direct integration into the packaging of the load IC.

The Fe1038D includes an 8-phase buck converter with fully integrated powertrain, including Ferric’s magnetic thin-film power inductors. The Fe1038D is a flip-chip die with low profile (150μm) and integrates digital interface, power management, voltage control and power train circuitry. The Fe1038D achieves high efficiency over wide load conditions, and low peak-to-peak output voltage ripple. The buck delivers up to 3A continuous output current at an output voltage range of 0.6V to 1.5 V, all in one FC (Flip Chip) 59 Cu bump, 2.0mm x 3.2mm die.

“The Fe1038D multi-phase DC-DC buck converter with fully integrated inductors allows customers to implement new designs with significantly smaller form factors, lower power consumption, and a lower overall bill of materials cost” according to Noah Sturcken, President and CEO of Ferric, Inc. “Ferric’s mobile, FPGA, and embedded solutions customers of the Fe1038D are creating their next generation products that will be much smaller and more efficient than currently available solutions.”
