These converters require a minimum 10% loading on their primary output and 20% loading
on each auxiliary output to maintain specified regulation. Operation under no-load conditions
will not damage these devices; however they may not meet all listed specifications.
"Full load" varies by part number and is determined by the input voltage range as indicated by
the part number suffix. See Technical Notes and Output Power Considerations.
Application-specific input/output filtering can be recommended or perhaps added internally
upon request. Contact DATEL Applications Engineering for details.
Applying a voltage to the On/Off Control pin when no input power is applied to the converter
can cause permanent damage to the converter. If desired, the On/Off Control function can be
replaced with a Sync function. See page 6 of this data sheet for more details.
Filtering and Noise Reduction
All TPB 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications without the use of external input/output capacitors. In critical
applications, input/output ripple and noise may be further reduced by
installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 6, 7
or 9) and Common (pin 8). The caps should be located as close to the
power converters as possible. See Figure 7. Typical values are listed in the
tables below. In many applications, using values greater than those listed
will yield better results.
To Reduce Input Ripple
Q12, D24 Models
47F, 50V
Q48, D48 Models
10F, 100V
To Reduce Output Ripple
+5V Output
47F, 10V, Low ESR
±12/15V Outputs
22F, 20V, Low ESR
In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these devices to meet your specific require-
ments. Contact our Applications Engineering Group for additional details.
Input Fusing
Certain applications and/or safety agencies may require the installation of fuses
at the inputs of power conversion components. For DATEL TPB
DC/DC Converters, you should use slow-blow type fuses with values no
greater than the following:

Q48/D48 Models
88 Volts
Input Reverse-Polarity Protection
Current must be <6A. Brief
duration only. Fusing recommended.
Output Overvoltage Protection
+5V Output
6.8 Volts, limited duration
±12V Outputs
15 Volts, limited duration
±15V Outputs

Output Current
Current limited. Max. current and
short-circuit duration are model
dependent.
Storage Temperature

Lead Temperature (soldering, 10 sec.)
+300°C
These are stress ratings. Exposure of devices to any of these conditions may adversely
affect long-term reliability. Proper operation under conditions other than those listed in the
Performance/Functional Specifications Table is not implied.
