DESCRIPTION
The NDL series is a range of high performance
miniature DC/DC converters having regulated out-
puts over the wide temperature range of -40ºC to
85ºC. The input voltage range is 2:1 with the output
power at 2 watts and the input to output isola-
tion is 1kVDC. Continuous short circuit protection,
external control and extremely small SIP packaging
provide state of the art functionality. Nominal input
voltages of 5, 12, 24 and 48V with output voltages
of 5,9,12 and 15V are available as standard with
custom parts on request. The plastic case is rated
to UL94V-0 with encapsulant to UL94V-1.
