Cross regulation is measured with the output being tested at 50% load. The second output is varied from 10% to 100% load. 2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 4.7 - 10 µF) be placed from the +VOUT to the -VOUT pins for single output models; or from each output to common for dual output models. 3. Transient recovery is measured to within a 1% error band for a load step change of 25%. 4. Short circuit protection is provided by a “hiccup mode” circuit. 5. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. THe control circuit is referenced to the minus (-) input. 6. 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. 7. These units should not be operated over +85°C. Exceeding +85°C may damage the unit. 8. 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. External Trim, UP Derating Curve, Without Heatsink External Trim, Down Derating Curve, With Heatsink A simple external circuit may be used to adjust the converter output ±10%. The trim circuit is illustrated in the diagrams above. The following formulas may be used to calculate the correct resistor value. To trim the output up, the correct resistor value (in k) equals: A xR RUP = R2 - A2 - R3 Where: A = 2.5 xR1 VADJ - 2.5 To trim the output down, the correct resistor value (in k) equals: A xR RDWN = R1 - A1 - R3 Where: A = VADJ - 2.5 xR2 2.5 Other equation values are: R1 R2 R3 VADJ Unit Output Voltage 5V 12V 15V 2.883 10.971 14.497 2.864 2.864 2.864 10.0 17.8 17.8 Amount of Adjustment For the heatsink option, add suffix “H” to the model number (i.e. MF3024S-05ERU-H) 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected] www.micropowerdirect.com EMC Specifications Parameter Radiated Emissions Conducted Emissions ESD RS EFT Surge CS Voltage Dips Standard See Note 1 EN 55022 See Note 1 EN 55022 EN 61000-4-2 EN 61000-4-3 See Note 2 EN 61000-4-4 See Note 3 EN 61000-4-5 EN 61000-4-6 EN 61000-4-29 Class A Class A Criteria B; ±4 kV Contact Criteria A; 10V/m Criteria B; ±2 kV Criteria B; ±2 kV Criteria A; 3 Vrms Criteria B; 0% - 70% Notes: 1. All units are rated for EN 55022 (CE/RE) class A without external components. They will meet class B with the addition of the MDCFM-1B (or a similar discrete filter circuit). Contact the factory for more information. 2. TomeettherequirementsofEN61000-4-4(±2kV),externalcomponentsareneeded, as shown on the typical connection diagram below. Use the MDCFM-1B to meet EN 61000-4-4 (±4 kV). Contact the factory for more information. 3. To meet the requirements of EN 61000-4-5 (±2 kV), external components are needed. This can be done discretely, or with the addition of the MDCFM-1B. Contact the factory for more information. Typical Connection Typical Board Layout: With External Filter/Surge Components for Single Output Unit The diagram at left illustrates a typical connection of the MF3000xERU series for applications that require meeting EMC standards. The units do not require external components to operate as specified. Some notes on this diagram (starting with the input circuit) 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 below. 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 below. 4. The output filtering capacitor (C5) 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. The board layout illustrations at left show connections for single and dual output units. Voltage derating of capacitors should be 80% or above. 5. Recommended values for components are: Component MOV L1 TVS C1 C2 L2 C3 C4, C5 Typical Board Layout: With External Filter/Surge Components for Dual Output Unit 24 VIN 10D560k 56 µH SMCJ48A 120 µF/50V 4.7 µF/50V 2.2 mH 4.7 µF/50V 1.0 nF/2 kV 48 VIN 10D101k 56 µH SMCJ90A 120 µF/100V 2.2 µF/100V 2.2 mH 2.2 µF/100V 1.0 nF/2 kV 6. In many applications simply adding input/output capacitors will enhance the input surge protection and reduce output ripple sufficiently. The input capacitor C1 and output capacitors C6 and C7 shown in the typical connection diagram above, and board layout drawings at left their connection. In this case, recommended capacitor values are: CIN: 10 µF for 24V input models 10 µF for 48V input models COUT: 10 µF for 5VOUT models 4.7 µF for 12/15VOUT models 8. The pad spacing between input/output (C4 & C5) in the board layout drawings below should be a minimum of 2 mm.
