ULE Series  
Isolated, High Density, Eighth-Brick  
1.25–20 Amp, DC-DC Converters  
FUNCTIONAL SPECIFICATION NOTES  
1. All models are tested and specified with external 1||10 μF ceramic/tantalum output  
capacitors and a 22 μF external input capacitor. All capacitors are low ESR types.  
These capacitors are necessary to accommodate our test equipment and may not  
be required to achieve specified performance in your applications. The ULE-12/4.2  
and ULE-24/3 modules require minimum load; all other models regulate within spec  
and are stable under no-load to full load conditions. General conditions for Specifi-  
cations are +25 deg.C, VIN=nominal, VOUT=nominal, full load. Adequate airflow must  
be supplied for extended testing under power.  
8. Output noise may be further reduced by adding an external filter. See I/O Filtering  
and Noise Reduction.  
9. All models are fully operational and meet published specifications, including “cold  
start” at –40ºC.  
10. Regulation specifications describe the deviation as the line input voltage or output  
load current is varied from a nominal midpoint value to either extreme.  
11. Alternate pin length and/or other output voltages are available under special quantity  
order.  
2. Input Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input  
filtering is CIN=33 μF tantalum, CBUS=220 μF electrolytic, LBUS=12 μH.  
3. Note that Maximum Power Derating curves indicate an average current at nominal  
input voltage. At higher temperatures and/or lower airflow, 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 fixed conditions, Tpcboard=+25ºC, full output load, natural air convection.  
5. The On/Off Control is normally controlled by a switch. But it may also 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 or open  
drain transistor.  
12. Electronic overvoltage shutdown is not included on 48V input models to comply  
with certain telecom reliability requirements. These requirements attempt continued  
operation despite input overvoltage. The converter is rated only to the maximum  
input voltage.  
13. Do not exceed maximum power specifications when adjusting the output trim.  
14. At zero output current, the output may contain low frequency components which  
exceed the ripple specification. The output may be operated indefinitely with no load.  
15. If reverse polarity is accidentally applied to the input, a body diode will become  
forward biased and will conduct 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.  
16. Output current limit is non-latching. When the overcurrent fault is removed, the  
converter will immediately recover.  
17. The Sense inputs are not included on lower current output models.  
18. ULE-5/12-D24 IOUT=8A max. if VIN=19-20V.  
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..
