Delphi ND Series Non-Isolated Point of Loadwww.DataSheet4U.com
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.
