➀ 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.

➁ "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.

➂ 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.

➃ Listed specification is for input-to-output isolation. Input-to-case and output-to-case

isolation is 1000Vdc, minimum.

TECHNICAL NOTES

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 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.

In critical, space-sensitive applications, DATEL may be able to tailor the

internal input/output filtering of these units 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 TMP DC/DC

Converters, you should use slow-blow type fuses with values no greater than

the following:
