When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF) be placed from the +VOUT to the -VOUT pins. 2. Transient recovery is measured to within a 1% error band for a load step change of 25%. 3. Short circuit protection is provided by a “hiccup mode” circuit. 4. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The maximum control current to the on/off 5. These units should not be operated with a load under 5% of full load. Operation at no-load will not damage the unit, but they may not meet all specifi cations. 6. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating.

This can also be accomplished by using external fi lter components as shown in the board layout drawing below. Some notes on these components are: 1. It is recommended that an external fuse be used. The recommended fuse is shown in the model chart on page 2. 2. An external MOV is recommended on the input to protect the unit in the event of a surge. A recommended value is given in the table at right. 3. An external TVS is recommended on the input to protect the unit in the event of a voltage spike. A recommended value is given in the table at right. 4. The output fi ltering capacitor (C 3) is a high frequency, low resistance electrolytic capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specifi cation for the unit. Voltage derating of capacitors should be 80% or above. Notes: 1. With a pulse interval that is >60S. Requires the addition of the fi lter module MDCFM-40U (or a similar discrete fi lter circuit) as shown in the circuit/ board layout diagrams below. Contact the factory for more information. 2. With a pulse interval that is >60S. Requires the addition of the fi lter module MDCFM-40U (or a similar discrete fi lter circuit) as shown in the circuit/ board layout diagrams below. Contact the factory for more information. 3. All units will meet class B with the addition of the MDCFM-40U (or a similar discrete fi lter circuit) as shown in the circuit/board layout diagrams below. Contact the factory for more information. 4. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed. This can be done discretely, or with the addition of the MDCFM-40U. Contact the factory for more information. 5. To meet the requirements of EN 61000-4-5 (±2 kV/±4 kV), external com- ponents are needed. This can be done discretely, or with the addition of the MDCFM-40U. Contact the factory for more information. Typical Board Layout: With External Filter/Surge Components 5.

Input noise and surge suppression modules are available for a number of MPD DC/ DC power supplies. For use with the MRxx11S product series, the MDCFM-40U DC fi lter modules are recommended. For pricing or full technical information, please contact the factory. 7. In many applications simply adding input/output capacitors will enhance the input surge protection and reduce output ripple suffi ciently. In this case, the capacitors C 1 and C3 would be connected as shown without the other fi lter compo- nents. Recommended capacitor values are given in the table at right.
