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.

PRODUCT OVERVIEW
The NMJ series are dual and single 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 NMJ
series is UL60950 recognized and suitable for
applications where safety and miniaturisation
are of paramount importance. Isolation barrier
approved for supplementary/reinforced insulation
