RO-MIL-2214 is a compact, high efficiency, low power DC-DC converter. Operating from 28V it has a wide range, 15V to 50V, over the full temperature range without derating. The unit is unconditionally stable and does not require any external components for correct operation.


Compact size and high efficiency are achieved by applying innovative techniques proved in our many avionic programmes. Efficiency is optimised across the full range of loads.


Over-voltage protection, remote disable and syncronisation to an external clock, primary side overload protection and over-voltage protection are all included. 


Optional flanges are available, with two clearance holes provided to optimise thermal impedance and vibration support.
