DESCRIPTION
The NKE sub-miniature series of DC/DC
Converters is particularly suited to isolating
and/or converting DC power rails. A smaller
package size, improved efficiency, lower
output ripple and 3kVDC isolation capability
through state of the art packaging and
improved technology. The galvanic isolation
allows the device to be configured to provide
an isolated negative rail in systems where
only positive rails exist. The wide temperature
range guarantees startup from –40°C and full
1 watt output at 85°C.

For DIP package style replace suffix S with D, eg NKE0303D.
When operated with additional external load capacitance the rise time of the input voltage will determine the
maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the
greater the maximum value of the additional external capacitance for reliable start up.
NKE0505SE offers higher efficiency than NKE0505S but over a narrower operating temperature range. See
temperature characteristics graph.
1 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2 See derating curve.
3 12V input types have typically 3% less load regulation change.
4 Supply voltage must be discontinued at the end of the short circuit duration.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
