Evaluation Procedure
(DEP-008 A)

The Delphi DNS Series of SIP type
POL converters


The DNS, 2.4~5.5V or 10~14V input,
programmable output,

non-isolated point of load

DC/DC converters, are the latest offering from
one of the world’s largest power supply
manufacturers

―

Delta Electronics, Inc. The

DNS 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. 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. All models
possess a myriad of standard protection
features.

This document guides the user through the
evaluation procedures to qualify a POL module.
The data shown in this Evaluation Procedure is
for the SIP Package Type POL evaluation board.
Please refer to the appropriate technical data
sheet for detailed performance and technical
information for the specific POL units.
