MKW1000 series of DC/DC converters, comprising 24

different models, is designed for a wide range of applications
including 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 10W of power into a 2 x 1 x 0.4 inch package, with

efficiencies as high as 83%, the MKW1000 has wide input ranges of
9-18VDC, 18-36VDC and 36-75VDC and is available in output
voltages of 3.3V, 5V, 12V, 15V, 24V, {5V, {12V and {15V.

Other feathers include continuous short circuit protection,

six-side shielded 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. Specifications subject to change without notice.
