4:1 input SIP DC/DC converters deliver 9W

June 19, 2017 // By Julien Happich
MicroPower Direct's MD900xRU series packs 9W of regulated output power in a miniature SIP package.

Eighteen models operate from 4:1 inputs of 9 - 36 VDC, and 18 - 75 VDC, providing single and dual outputs of 3.3, 5, 9, 12, 15, 24, ±5, ±12 or ±15 VDC. Standard features include efficiency to 89% an input/output isolation of 1,600 VDC, a remote on/off control input and low noise operation. All models are protected for over voltage, over current and short circuit faults. The MTBF of the MD900xRU series (per MIL HDBK 217F) is over 1.0 Mhours.

All models of the MD900xRU family are packaged in a miniature SIP case that measures just 21.8x9.6x11.2mm 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°C to +85°C with no heat sinking required. Cooling is by free-air convection.
