Delphi DNL, Non-Isolated Point of Load
DC/DC Power Modules: 8.3-14Vin, 0.75-5.0V/20A out
The Delphi series DNL, 8.3~14V input, single output, non-isolated point
of load DC/DC converters are the latest offering from a world leader in
power systems technology and manufacturing
―
Delta Electronics, Inc.
The DNL series provides a programmable output voltage from 0.75V to
5.0V through an external trimming resistor. The DNL converters have
flexible and programmable tracking and sequencing features to enable a
variety of sequencing and tracking between several point of load power
modules. This product family is available in a surface mount or SIP
package and provides up to 20A of output current in an industry standard
footprint and pinout. With creative design technology and optimization of
component placement, these converters possess outstanding electrical
and thermal performance and extremely high reliability under highly
stressful operating conditions.
