These converters require a minimum 10% loading on their primary output and 20%
loading on each auxiliary output to maintain specied regulation. Operation under no-load
conditions will not damage these devices; however they may not meet all listed specica
tions.
"Full load" varies by part number and is determined by the input voltage range as indi
cated by the part number sufx. See Technical Notes and Output Power Considerations.
Filtering and Noise Reduction
All TMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specications without the use of external input/output capacitors. In criti-
cal 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
47μF, 50V
Q48, D48 Models
10μF, 100V
To Reduce Output Ripple
+5V Output
47μF, 10V, Low ESR
±12/15V Outputs
22μF, 20V, Low ESR
In critical, space-sensitive applications, DATEL may be able to tailor the in-
ternal input/output ltering of these units to meet your specic requirements.
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 TMP DC/
DC Converters, you should use slow-blow type fuses with values no greater
than the following:
VIN Range
Fuse Value
Q12
4A
D24
4A
Q48
3A
D48
2A
Input Voltage:
Q12/D24 Models
44 Volts
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
18 Volts, limited duration
Output Current
Current limited. Max. current and
short-circuit duration are model
dependent.
Storage Temperature
–40 to +105°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 Specications Table is not implied.
Absolute Maximum Ratings
TECHNICAL NOTES
Applying a voltage to the On/Off Control pin when no input power is applied to the con
verter can cause permanent damage to the converter.
Listed specication is for input-to-output isolation. Input-to-case and output-to-case
isolation is 1000Vdc, minimum.
