Delphi DCL, Non-Isolated Point of Load
DC/DC Power Modules: 6~14Vin,
0.8V-3.3V/30Aout
The Delphi Series DCK, 6-14V 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 DCK series provides a programmable output voltage from 0.8 V to
3.3 V 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 and provides up to 30A 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.
OPTIONS
Negative/Positive on/off logic
Vo Tracking feature
