Delphi DNL10, Non-Isolated Point of Load
DC/DC Power Modules: 8.3-14Vin, 0.75-5.0V/20A out
The Delphi series DNL10, 8.3~14V input, single output, 20A non-isolated
point of load DC/DC converter in surface mounted package is the latest
offering from a world leader in power systems technology and
manufacturing
―
Delta Electronics, Inc. The DNL10 series provides a
programmable output voltage from 0.75V to 5.0V through an external
trimming resistor. The DNL10 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.
