Delphi NE Series Non-Isolated Point of Load DC/DC Modules:

The Delphi NE 6A Series, 3.1~13.8V wide input, wide trim 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 NE product family is

the second generation, non-isolated point-of-load DC/DC power

modules which cut the module size by almost 50% in most of the

cases compared to the first generation NC series POL modules. The

NE 6A product family provides an ultra wide input range to support

3.3V, 5V, 8V, 9.6V, and 12V bus voltage point-of-load applications and

it offers up to 6A of output current in a vertically or horizontally

mounted through-hole miniature package and the output can be

resistor trimmed from 0.59Vdc to 5.1Vdc. 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.
