DESCRIPTION
The NMJ series are dual output DC/DC
converters in a 7 pin SIP package style
offering pin and functionality compatibility
with the NMV series SIP DC/DC converters.
The series was tested by British Standards
Institute (BSI) and received certificate number
8105 issue 2 confirming compliance with BS
EN 60950 and IEC 950 safety standards for
reinforced insulation. The NMJ series is
suitable for applications where safety and
miniaturisation are of paramount importance.
EN 60950 is derived from IEC 950 and is
equivalent to UL 1950 and CSA 950
standards.

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.
