FEATURES s 3kVDC Isolation (1 minute) s Single or Dual Output s Industry Standard Pinout s Power Sharing on Dual Output s Efficiency to 80% s Power Density up to 0.90W/cm3 s 24V & 48V Input s 5V, 9V, 12V and 15V Output s Footprint from 1.17cm 2 s UL 94V-0 Package Material s No Heatsink Required s Internal SMD Construction s Toroidal Magnetics s Fully Encapsulated s No External Components Required s Custom Solutions Available s No Electrolytic or Tantalum Capacitors DESCRIPTION
The NMV Series offers single or dual output versions in the same size package as the popular NMA series. The higher isolation is particularly useful in control type applications where the standard 1kV is not sufficient.

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.
