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.
