RO-MIL-2220 is a compact, high efficiency, dual output DC-DC converter. Operating from a 28V input it has a wide input voltage range of 15 to 50V (with 80V surge rating) and operates over the 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 voltage sensing and a remote disable facility. Although they do not have to be connected for the unit to function, the remote sense terminals allow the output voltage to be regulated directly at the load. This compensates for the losses of the output power leads and provides optimum regulation.
