MTBF > 600,000 Hours
MKW5000-Series power modules are low-profile
dc-dc converters that operate over input voltage ranges of
18-36VDC and 36-75VDC and provide precisely regulated output
voltages of 2.5V, 3.3V, 5V, 5.1V, 12V, 15V,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 30W of power into a 2 x 1.0 x 0.4 inch package,
with efficiencies as high as 88%, the MKW5000 includes
continuous short circuit protection, overvoltage protection,
overtemperature protection, output trim function, remote on/off,
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.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.

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.
7. Other input and output voltage may be available,
please contact factory.
8. Specifications subject to change without notice.
9.To order the converter with Remote on/off
function ,please add suffix - RC ( EX :
MK5000(A)-RC).
