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 pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut 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 specifications. 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.

Suggested component values are: filter module is used to make the circuit compliant with input surge and EMC standards EN 55022, Component Value EN61000 and EN 50155. This can also be accomplished by using external filter components as MOV S14K130 shown in the board layout drawing below. Some notes on these components are: L1 56 µH 1. It is recommended that an external fuse be used. The recommended fuse is shown in the model chart on page 2. TVS SMCJ170A 2. An external MOV is recommended on the input to protect the unit in the event of a surge. A C1 100 µF/200V recommended value is given in the table at right. C3 1.0 µF/50V 3. An external TVS is recommended on the input to protect the unit in the event of a voltage L2 4.7 µH spike. A recommended value is given in the table at right. CY1, CY2 1,000 pF/2 kV 4. The output filtering capacitor (C3) is a high frequency, low resistance electrolytic capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specification 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 filter module MDCFM-40U (or a similar discrete filter 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 filter module MDCFM-40U (or a similar discrete filter 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 filter 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 components are needed. This can be done discretely, or with the addition of the MDCFM-40U. Contact the factory for more information. 6. 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 filter 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 Vin Input Output reduce output ripple sufficiently. (VDC) Capacitor Capacitor In this case, the capacitors C1 and C3 would be connected as shown 110 10 µF to 47 µF 10 µF without the other filter components. Recommended capacitor values are given in the table at right.
