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 series ensures

ease of upgradeability.

FEATURES

RoHS compliant

Efficiency from 81%

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 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
