FEATURES

■ 3kVDC Isolation (1 Minute)
i When operated without additional external load capacitance, the output voltage of the devices is guaranteed
to be within 95% of its steady state value within 100ms after the input voltage has reached 95% of its steady
state value, irrespective of the rise time of the input voltage.
ii 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.

The NTV series of 3kV isolation miniature
surface mounted DC-DC Converters employ
leadframe technology and transfer moulding
techniques to bring all of the benefits of IC

be placed and reflowed with IC’s, thus
reducing time and cost in production. The co-
planarity of the pin positions is based upon
IEC 191-6:1990. The devices are suitable for
all applications where high volume
