Delphi ND Series Non-Isolated Point of Load

DC/DC Power Modules: 12Vin, 0.9V~3.63Vout,

50Aout

The Delphi ND Series, 12V input, single output, non-isolated point of

load (POL) DC/DC converters are the latest offering from a world leader

in power systems technology and manufacturing — Delta Electronics,

Inc. The ND/NE product family is the second generation, non-isolated

point-of-load DC/DC power modules for the datacom/networking/IT

applications and it will help to cut the module size by 35% to 50%

compared to the first generation NC series POL modules. The ND/NE

product family provides 6A to 60A of output current in a vertically or

horizontally mounted through-hole package and the output can be

resistor trimmed from 0.9Vdc to 3.63Vdc. It provides a very cost

effective, high efficiency, and high density point of load solution. With

creative design technology and optimization of component placement,

these

converters

possess

outstanding

electrical

and

thermal

performance, as well as extremely high reliability under highly stressful

operating conditions.
