Minmax's MKW2600 series, comprising 10 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
9-36VDC, 18-75VDC and is available in output voltages of 3.3V,
5.1V, 12V, {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 at no-load will not damage these units.
However, they may not meet all specifications.
6. All DC/DC converters should be externally fused
at the front end for protection.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.

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 : MK2621-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. MKW2621A.
10. Specifications subject to change without notice.
