Minmax's MKW5000-Series power modules are low-profile dc-dc converters that operate over input voltage ranges of 18-36VDC and 36-75VDC which provide precisely regulatedoutput voltages of 2.5V, 3.3V, 5V, 5.1V, 12V and 15VDC, 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 30W of power into a 2x1x0.4inch package, with efficiencies as high as 88%, the MKW5000 includes continuous short circuit protection, overvoltage protection, output trim function, 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°C, resistive load, nominal input voltage, rated output current unless otherwise noted.
2. Transient recovery time is measured to within 1% error band for a load step change of 75% to 100%.
3. These power converters require a minimum output load to maintain specified regulation.
4. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed.
5. All DC/DC converters should be externally fused at the front end for protection.
6. Other input and output voltage may be available, please contact factory.
7. To order the converter with Remote On/Off function, please add a suffix -RC (e.g. MKW5030-RC).
8. To order the converter with EN55022 Class A function, please add a suffix A (e.g. MKW5030A).
9. All specifications subject to change without notice.
