The LT DC-DC Converter is Magnetek’s
solution for next generation , a wide variety
of applications including public and private
telecommunications and industrial systems.
The LT DC/DC Converter with input voltage
of 18-72 Vdc offers standard output of 12V .
Continuous short circuit protection,
overvoltage protection and 50mV output
ripple, conducted noise compliance
minimize design-in time, cost and eliminate
the need for external components.

NOTES
1) Vi = 48V.
2) Current must be < 2A. Brief duration only. Fusing recommended.
3) Maximum.
4) Low line to high line.
5) Full load to no load.
MagneTek
6) An optional internal filter is available, when the filter is added the 3W DC/DC Converter will meet
VDE0871-A, VDE0878-A and EN55022-A.
7) Conducted noise filtering to EN55022 level B may be accomplished by putting the follow capacitor
Across the input pins: 48Vdc………1µF ceramic X7R dielectric type.
