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. MKW5030-RC).
9.To order the converter with EN55022 Class A function, please add a suffix A (e.g. MKW5030A).
10. To order the converter with heatsink, please add a suffix H (e.g. MKW5030H).
11. Specifications subject to change without notice.

A: 2.5V, 3.3V, 5V and 5.1V-output models use the synchronous-rectifier configuration shown as above.
12V and 15V-output models employ a standard, diode-rectification architecture.
