Delphi DNT04, Non-Isolated Point of Loadwww.DataSheet4U.com
DC/DC Power Modules: 2.4~5.5Vin, 0.75~3.3Vo, 3A out
The Delphi Series DNT04, 2.4-5.5V 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 DNT04 series provides a programmable output
voltage from 0.75V to 3.3V using external resistors. This product family
is available in surface mount or SIP package and provides up to 3A 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.
The DNT04, 3A modules have excellent thermal performance and can
provide full output current at up to 85ambient temperature with no
airflow.
