Delphi DNS, Non-Isolated Point of Load
DC/DC Power Modules: 2.8-5.5Vin, 0.75-3.3V/6Aout
The Delphi Series DNS, 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 systems technology and manufacturing -- Delta
Electronics, Inc. The DNS series provides a programmable output
voltage from 0.75V to 3.3V using an external resistor and has flexible
and programmable tracking features to enable a variety of startup
voltages as well as tracking between power modules. This product
family is available in surface mount or SIP packages and provides up
to 6A of output current in an industry standard footprint. 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.
