Minmax's MKW2500 series, comprising 21 different models, has
been conceived as an application 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 2x1x0.4 inch package, with
efficiency as high as 86%, the MKW2500 has wide input ranges of
9-18VDC, 18-36VDC and 36-75VDC which is available in output
voltages of 3.3V, 5V, 5.1V, 12V, 15V, {12V and {15VDC.
Other feathers include continuous short circuit protection, remote
on/off, six-sided shielded case and EN55022 Class A conducted noise
compliance minimize design-in time, cost and eliminate the need for
external filtering.

Notes :
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 modules; however, they may not meet all
specifications listed.
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 a suffix -RC (e.g. MKW2521-RC).
9. To order the converter with EN55022 Class A
function, please add a suffix A (e.g. MKW2521A).
10. Specifications subject to change without notice.
