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.
