DC-DC Converters Are Intel VRM 11.1 Compatible

FDK has launched the VR Series of voltage regulator modules (VRM) with the announcement of 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 FPVR12CR50130PA is the first product in this series and delivers up to 130A of continuous output current with minimal derating and high efficiency.

The FPVR12CR50130PA converter operates from an 11.04V DC to 12.6V DC input, and provides an 8-bit VID programmable output voltage in the range of 0.5V DC to 1.6V DC. Benchmarked at an output voltage of 1.35V DC, it delivers the full rated continuous output current of 130A with no derating up to 40C with 400LFM (2m/s) airflow, at an efficiency of 87 per cent. To minimise capacitance needs, it has a power train comprising six interleaved phases, with an effective switching frequency of 2.4MHz.

The FPVR12CR50130PA is offered in a 3.78in x 0.728in (96mm x 18.5mm) card edge package, with a height of 1.177in (29.9mm). The low profile makes it suitable for applications with rack heights down to 1U, while occupying a footprint of 2.8in2 (18cm2). Standard features include remote On/Off, over-current and over-temperature protection, plus a light load mode to improve efficiency at low output current.
