Mini DC/DC converters offer 4:1 input, 9-W output

The MD900xRU DC/DC converter series packs 9 W of regulated output power in a miniature SIP package. These single- and dual-output DC/DC converters suit a wide range of board-level power distribution applications. 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 overvoltage, overcurrent, 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 0.86 x 0.38 x 0.44 in. (21.8 x 9.6 x 11.2 mm), yielding a power density of 44 W/in.³ . Each model is specified for operation over the industrial temperature range of –40°C to 85°C with no heat sinking required. Cooling is via air convection. The converter series suits board-level industrial power applications.
