MI-J00 military DC-DC converters provide 10 to 50W of output power in a compact 2.4 x 2.5 x 0.7 in3 (61 x 64 x 18 mm) package. They are designed to meet the requirements of MIL-STD-704D/E, 155Vdc per MIL-STD-1399A, and 270Vdc per MIL-STD-704D/E for 28Vdc input (MI-J20), 270Vdc input (MI-J60), and 155Vdc input, respectively. The MI-J00 family is also compliant to MIL-STD-810 environmental testing requirements for humidity, fungus, salt fog, explosive atmosphere, acceleration, vibration, and shock.
The MI-JOO TM series provides compact, high‑efficiency DC‑DC conversion for military applications, offering up to 90 % efficiency, remote‑sense capability, and low‑noise FM control. The units are sized 2.28" × 2.4" × 0.5" and are qualified for MIL‑STD‑810 environmental conditions.
Key specifications include a wide input voltage range, precise output regulation, high isolation ratings, and robust reliability data per MIL‑HDBK‑217F. The datasheet also lists semi‑custom module options and environmental limits such as operating temperature from –40 °C to +100 °C.
