Filtering and Noise Reduction
All TMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specifications 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

In critical, space-sensitive applications, DATEL may be able to tailor the in-
ternal input/output filtering of these units to meet your specific requirements.

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:
~ 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 specifica
 "Full load" varies by part number and is determined by the input voltage range as indi
cated by the part number suffix. See Technical Notes and Output Power Considerations.
