RO-MIL-2212 is a compact, high current, high efficiency, single-rail DC-DC converter. Operating from a 28V input it has a wide input voltage range of 16 to 40V and operates over the military 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.

 

Energy for the output is provided by an isolated high frequency PWM push-pull converter. Short-circuit and overvoltage protection is included as well as remote sensing and remote disable. If connected, the remote sense terminals allow the output to be regulated at the load itself. This compensates for the losses of the output power leads and provides optimum regulation. If not connected the units will still operate but regulation will occur at the unit pins.
