Start up time is measured at nominal input and with a constant resistive load. 2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins. 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. 6. These units should not be operated with a load under 10% 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 ModelSelection table above for the correct rating. Derating Curve, Output Voltage <5V External Trim Derating Curve, Output Voltage >5V External Trim Notes: On single output units, an external resistor can be used to adjust the converter output up/down by about 10%. The connection is shown in the diagram at left. The required resistor value is calculated by the formulas: Trim UP = RTRIM = A $-R2 - R3 R2 A Trim Down = RTRIM = A $-R1 - R3 R1 A Where A = VREF $ R1 VTRIM - VREF Where A = VTRIM VREF $ R2 VREF Where RTRIM = The value of the external trim resistor VTRIM = The amount of voltage adjustment required The value of R1, R2, R3 and VREF are given in the table below. 292 Page Street Ste D Stoughton, MA 02072 Output Trim Resistor Values Parameter R1 (k) R2 (k) R3 (k) VREF (V) 3.3 4.801 2.863 15.00 1.24 5.0 2.883 2.864 10.00 2.50 Output Voltage (VDC) 9.0 12 15 7.500 10.971 14.497 2.864 2.864 2.864 15.00 17.80 17.80 2.50 2.50 2.50 24 24.872 2.864 20.00 2.50 • 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.

Contact the factory for more information. 2. 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-0x. 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-0x.

Recommended values for components are: series for applications that require meeting EMC standards. The units do not Component 48 VIN 24 VIN require external components to operate as specified. Some notes on this MOV S14K35 S14K60 diagram (starting with the input circuit) are: L1 56 µH 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 SMCJ48A SMCJ90A 2. An external MOV is recommended on the input to protect the unit in the C1 330 µF/50V 330 µF/100V event of a surge. A recommended value is given in the table at right. C2, C3 4.7 µF/50V 2.2 µF/100V 3. An external TVS is recommended on the input to protect the unit in the L2 1.0 mH 1.0 mH event of a voltage spike. A recommended value is given in the table at C4, C5 1nF/2 kV 1nF/2 kV right. 4. The output filtering capacitor (C6) is a high frequency, low resistance C0 400 uF/200V 400 uF/200V electrolytic capacitor. Care must be taken in choosing this capacitor not to exceed the capacitive load specification for the unit. Voltage derating 6. Input noise and surge suppression modules are available for a number of MPD DC/DC power supplies. A connection for one of of capacitors should be 80% or above. these modules is illustrated in the typical board layout shown at the bottom of this page For pricing or full technical information, please contact the factory.
