DESCRIPTION
The NTE series of miniature surface mounted
DC-DC Converters employ leadframe
technology and transfer moulding techniques
to bring all of the benefits of IC style
packaging to hybrid circuitry. The devices are
fully compatible with CECC00802 to 280°C
which allows them to be placed and reflowed
with IC’s, thus reducing time and cost in
production. The co-planarity of the pin
positions is based upon IEC 191-6:1990.
The devices are suitable for all applications
where high volume production is envisaged.

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.
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.
5 If components are required in tape and reel format suffix order code with -R, e.g. NTE0505M-R
