description
The NMH Series of DC-DC Converters offer
the smallest footprint of any dual-output 2
Watt DC-DC Converter. Pin compatibility
with the NMA series ensures minimal effort
in upgrading distributed power systems.
The devices are suited to any application
where a dual rail supply is required in a
minimum of pcb space.
