description
The NML Series of DC-DC Converters is
particularly suited to isolating and/or converting
DC power rails. 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 2 watt
output at 85°C. Pin compatibility with the NME
and LME ensures ease of upgradeability.

When operated
without
additional external load capacitance, the output voltage of the NML 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.
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.
