DESCRIPTION
The NMR series of industrial temperature range
DC/DC converters are the standard building
blocks for on-board distributed power systems.
They are ideally suited for providing single rail
supplies on primarily digital boards with the added
benefit of galvanic isolation to reduce switching
noise. Surface mount technology and advanced
packaging materials produce rugged reliable
performance over an extended temperature range
from -40ºC to 85ºC. For the NMR100PC protection
is continuous and auto-resetting on removal of the
short circuit.
