Minmax's MKW2500 series, comprising 18 different models, has
been conceived as an applications specific range of DC/DC
converters, specially addressing data communication equipments,
mobile battery driven equipments, distributed power systems,
telecommunication equipments, mixed analog/digital subsystems,
process/machine control equipments, computer peripheral systems
and industrial robot systems.
Packing up to 15W of power into a 2 x 1 x 0.4 inch package, with
efficiency as high as 86%, the MKW2500 has wide input ranges of
9-18VDC, 18-36VDC and 36-75VDC, and is available in output
voltages of 3.3V, 5.1V, 12V, 15V, {12V and {15V.
Other feathers include continuous short circuit protection, remote
on/off,six-side shieled case and EN55022 level A conducted noise
compliance minimize design-in time,cost and eliminate the need for
external components.

Note :
1. Specifications typical at Ta=+25], resistive load,
nominal input voltage, rated output current unless
otherwise noted.
2. Transient recovery time is measured to within 1%
error band for a step change in output load of 75%
to 100%.
3. Ripple & Noise measurement bandwidth is 0-20
MHz.
4. These power converters require a minimum
output loading to maintain specified regulation.
5. Operation under no-load conditions will not
damage these devices; however they may not
meet all listed specifications.
6. All DC/DC converters should be externally fused
at the front end for protection.
7. Other input and output voltage may be available,
please contact factory.
8.To order the converter with Remote on/off function
,please add suffix - RC ( EX : MK2521-RC )
9. An optional internal filter is available. When the
filter is added, the MKW2500 will meet
EN55022-A. Add the suffix " A" to the model
number, e.g. MKW2521A.
10. Specifications subject to change without notice.
