Point-of-load DC-DC converters for military embedded systems introduced by Murata Power

MANSFIELD, Mass., 27 May 2012. Murata Power Solutions Inc. in Mansfield, Mass., is introducing the OKX series of miniature non-isolated single-output DC-DC converters for point-of-load applications in military embedded systems involving field-programmable gate arrays (FPGAs) and digital signal processors (DSPs).

The converters can operate in temperatures from -40 to 85 degrees Celsius. Typical embedded computing applications include powering CPUs, data communications, telecommunications, server and storage equipment, industrial systems, programmable logic, and mixed voltage designs.

Within the OKAMI OKX series are four models that provide 3- or 5-amp outputs with either 5- or 12-volt nominal inputs. The OKX-T/3 and OKX-T/5 series additions are packaged in 5-pin single-in-line packages.

Measuring 22.9 by 10.2 by 7.1 millimeters, the package meets Distributed-Power Open Standards Alliance (DOSA) specifications and is designed as a drop-in replacement for other DOSA-compliant parts.

These power converters typically have efficiencies of 94.5 percent at 3.3 volts output, and can drive ceramic capacitive loads as strong as 1,000 uF, and have tight load regulation. The output voltage is programmable from 0.75 to 3.63 volts DC for the 5-volt input part, and as much as 5 volts DC for the 12-volt input part.

Features include input under voltage lockout, output short circuit, output over current, and over-temperature protection. The on/off control feature also is standard in positive or negative logic.

The modules are RoHS-compliant and meet the international safety standard UL/EN/IEC 60950-1 for IT and commercial equipment.
