To avoid danger to persons or equipment and to retain safety certifi cation, the user must connect an external fast-blow input fuse as listed in the specifi cations. Be sure that the PC board pad area and etch size are adequate to provide enough current so that the fuse will blow with an overload. Start-Up Considerations When power is fi rst applied to the DC/DC converter, there is some risk of start up diffi culties if you do not have both low AC and DC impedance and adequate regulation of the input source. Make sure that your source supply does not allow the instantaneous input voltage to go below the minimum voltage at all times. Even if this voltage depression is very brief, this may interfere with the on-board controller and possibly cause a failed start. Use a moderate size capacitor very close to the input terminals. You may need two parallel capacitors. A larger electrolytic or tantalum cap supplies the surge current and a smaller parallel low-ESR ceramic cap gives low AC impedance. Remember that the input current is carried both by the wiring and the ground plane return. Make sure the ground plane uses adequate thickness copper. Run additional bus wire if necessary.

All capacitors are low ESR types. These capacitors are necessary to accommodate our test equipment and may not be required to achieve specifi ed performance in your applications. All models are stable and regulate within spec under no-load conditions. General conditions for Specifi cations are +25°C, VIN = nominal, VOUT = nominal, full load. (2) Input Ripple Current is tested and specifi ed over a 5 Hz to 20 MHz bandwidth. Input fi ltering is CIN = 33μF/100V tantalum, CBUS = 220μF/100V electrolytic, LBUS = 12μH. (3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher temperatures and/or lower airfl ow, the DC/DC converter will tolerate brief full current outputs if the total RMS current over time does not exceed the Derating curve. All Derating curves are presented at sea level altitude. Be aware of reduced power dissipation with increasing density altitude. (4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fi xed conditions, TPCBOARD = +25°C, full output load, natural air convection. (5) The On/Off Control may be driven with external logic or by applying appropriate external voltages which are referenced to Input Common. The On/Off Control Input should use either an open collector/open drain transistor or logic gate which does not exceed +13.5V. (6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting. (7) The outputs are not intended to sink appreciable reverse current. (8) Output noise may be further reduced by adding an external fi lter. See I/O Filtering and Noise Reduction. (9) All models are fully operational and meet published specifi cations, including “cold start” at –40°C. (10) Regulation specifi cations describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme. (11) If reverse polarity is accidentally applied to the input, a body diode will become forward biased and will accept considerable current. To ensure reverse input protection with full output load, always connect an external input fuse in series with the +VIN input. Use approximately twice the full input current rating with nominal input voltage. (12) Input overvoltage shutdown on 48V input models is normally deleted in order to comply with certain telecom reliability requirements. These requirements attempt continued operation despite signifi cant input overvoltage. (13) Note that the converter may operate up to +110°C PCB temperature with the baseplate installed. However, thermal self-protection occurs near +125°C and there is a temperature gradient from high power components. Therefore, +100°C baseplate temperature is recommended to avoid thermal shutdown. (14) “Extreme accuracy” refers to all combinations of line and load regulation, output current, initial setpoint accuracy and temperature coeffi cient.
