DESCRIPTION
The NTV series of 3kV isolation 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 circuitr y. The
devices are fully compatible with
CECC00802 to 280掳C which allows them to
be placed and reflowed with IC鈥檚, 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.

i When operated
without
additional external load capacitance, the output voltage of the devices is guaranteed
to be within 95% of its steady state value within 100ms after the input voltage has reached 95% of its steady
state value,
irrespective of the rise time of the input voltage.
ii 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.

Calculated using MIL-HDBK-217F with nominal input voltage at full load.
See derating curve.
12V input types have typically 3% less load regulation change.
Supply voltage must be discontinued at the end of the short circuit duration.
If components are required in tape and reel format suffix order code with -R, e.g. NTV0505M-R.
