FEATURES
UL 60950 recognised Efficiency from 80% Wide temperature performance at full 2 Watt load, –40°C to 85°C UL 94V-0 package material Industry standard pinout 1kVDC isolation 5V, 12V, 15V & 24V input 5V, 9V, 12V, & 15V output Internal SMD construction Fully encapsulated with toroidal magnetics No external components required MTTF up to 3.9 million hours Pin compatible with NMR series No electrolytic or tantalum capacitors
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 NMG series of DC/DC Converters is particularly suited to isolating and/or converting DC power rails. The galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist. The wide temperature range guarantees startup from –40°C and full 2 watt output at 85°C. Pin compatibility with the NMR and MER1 series ensures ease of upgradeability.
