Compact DC/DC converters provide 15-W output

Operating from a 4:1 input range, the MB1500ERU series DC/DC converters provide 15-W output power in a compact 1 x 2-in. case. These units suit board-level power applications requiring compact size, a robust performance envelope, and operation over a wide input range. It can also be used with multiple input sources, such as 24- and 48-V battery systems.

Fifteen models operate from wide 4:1 input ranges of 9 to 36 or 18 to 75 Vdc, providing tightly regulated single and dual outputs of 3.3, 5, 12, 15, 24, ±5, ±12, or ±15 Vdc. Standard features include an input/output isolation of 1,500 Vdc, tight line/load regulation, and efficiency as high as 90%. All units meet EN 55022 Class A and include a remote on/off control input. The MTBF (per MIL HDBK 217F) of the converter series is greater than 1.0 Mh. The MB1500ERU family is packaged in a 2 x 1 x 0.4-in. shielded metal case. The pin-out is industry standard. Each model is specified for operation over the wide operating industrial temperature range of –40°C to 60°C with no derating. An optional heatsink extends the range to 65°C.
