FDK Intros Voltage Regulator Modules
Edge-card DC-DC converter.
San Jose, CA — FDK Corporation (Tokyo Stock Exchange 2nd Section: Code 6955), has introduced its VR Series of voltage regulator modules (VRM) with the FPVR12CR50130PA DC-DC converter. Designed to meet the power needs of high-end microprocessors and related devices in servers, workstations, supercomputers and storage, the VR Series converters are compatible with the Intel® VRM 11.1 specification. The product is the first in this series and delivers up to 130 Amp of continuous output current with minimal derating and high efficiency.

The converter operates from an 11.04 to 12.60VDC input, and provides an 8-bit VID programmable output voltage in the range of 0.50 to 1.60VDC. Benchmarked at an output voltage of 1.35VDC, it delivers the full rated continuous output current of 130A with no derating up to 40°C with 400LFM (2m/s) airflow, at an efficiency of 87 percent. To minimize capacitance needs, it has a power train comprising six interleaved phases, with an effective switching frequency of 2.4MHz.

The unit is offered in a 3.780 x 0.728-in. (96.0 x 18.5mm) card edge package, with a height of 1.177-in. (29.9mm). The low profile makes it suitable for applications with rack heights down to 1U, while occupying a footprint of only 2.8 in2 (18cm2). Standard features include remote ON/OFF, over-current and over-temperature protection, and a light load mode to improve efficiency at low output current.
