Delphi DNL, Non-Isolated Point of Load
DC/DC Power Modules: 2.8-5.5Vin, 0.75-3.3V/16A out
The Delphi Series DNL, 2.8-5.5V input, single output, non-isolated Point
of Load DC/DC converters are the latest offering from a world leader in
power system and technology and manufacturing -- Delta Electronics,
Inc. The DNL series provides a programmable output voltage from 0.75V
to 3.3V using an external resistor. The DNL converters have flexible and
programmable tracking and sequencing features to enable a variety of
startup voltages as well as sequencing and tracking between power
modules. This product family is available in a surface mount or SIP
package and provides 16A of current in an industry standard footprint.
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.
