The MD900xRU series of 4:1 input, 9W DC/DC converters can save board real estate by virtue of the single inline package (SIP), adopted by Micropower Direct for its latest converter series.

The MD900xRU series packs 9W of regulated output power in a miniature SIP package. The low cost, single and dual output DC/DC converters provide the small size, high performance features, power density and economy required by a wide range of board level power distribution applications, says Micropower Direct.

There are 18 models in the series, operating from 4:1 inputs of 9.0 to 36V DC, and 18 to 75V DC, providing single and dual outputs of 3.3, 5.0, 9.0, 12, 15, 24, ±5.0, ±12 or ±15V DC.

Standard features include efficiency to 89 per cent, an input/output (I/O) isolation of 1,600V DC, a remote on/off control input and low noise operation.

All models are protected for over-voltage, over-current and short circuit faults. The mean time between failure (MTBF) of the MD900xRU series (per MIL HDBK 217F) is over one Mhours.

All models of the MD900xRU family are packaged in a miniature SIP case that measures just 0.86 x 0.38 x 0.44-inch (21.8 x 9.6 x 11.2mm), yielding a power density of 44W per cubic inch.

The pin out is industry standard and all case materials meet UL94-V0 requirements. Each model is specified for operation over the industrial temperature range of -40 to +85 degree C with no heat sinking required. Cooling is by free-air convection.

All MicroPower Direct products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all products as a routine part of our production process.
