Minmax's MKW3000 series, comprising 18 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 20W of power into a 2x1x0.4 inch package, with
efficiency as high as 89%, the MKW3000 has wide input ranges of
9-18VDC, 18-36VDC and 36-75VDC and is available in output voltages
of 3.3V, 5V, 12V, 15V, {12V and {15VDC.
Other feathers include continuous short circuit protection, overvoltage
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.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.

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. Specifications subject to change without notice.
9. To order the converter without Remote On/Off
function, please add a suffix -N
(e.g.MKW3021-N).
