PRODUCT OVERVIEW

The NXE1 series is a new range of low cost, lower

proﬁle, fully automated manufacture surface

mount DC/DC converters. The NXE1 series

automated manufacturing process with substrate

Embedded Transformer, offers increased product

reliability and repeatability of performance in a

halogen free, iLGA inspectable package. The NXE1

series, industry standard footprint is compatible

with existing designs.

The NXE1 series has a MSL rating 2, and is com-

patible with a peak reﬂow solder temperature of

245˚C as per J-STD-020 and J-STD-075.

NXE1 Series Isolated 1W Single Output SM DC/DC Converters TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.

NXE1 Series Isolated 1W Single Output SM DC/DC Converters APPLICATION NOTES Short Circuit Performance NXE1 series offers short circuit protection which is continious with nominal input voltage at low ambient temperatures. At higher ambient temperatures of 65 °C and above short circuit duration will be limited. Advisory Notes Minimum Load The NXE1 series is not hermetically sealed, customers should ensure that parts are fully dried before input power application.
