Delphi D12S05020-1 Non-Isolated Point of
Load
DC/DC Modules:
4.5V~13.2Vin, 0.59V~5.0Vout, 20A
The Delphi D12S05020-1 Series, 4.5V to 13.2V wide input, wide trim,
single output, non-isolated point of load (POL) DC/DC converters are
the latest offering from a world leader in power systems technology
and manufacturing
—
Delta Electronics, Inc. The D12S05020-1
product family is part of the second generation, non-isolated
point-of-load DC/DC power modules for the data communication
applications which cut the module size by almost 50% in most of the
cases compared to the first generation NC series POL modules. The
D12S05020-1 product family provides an ultra wide input range to
support 5V, 8V, 9.6V, and 12V bus voltage point-of-load applications
and it offers 20A of output current in a vertically mounted through-hole
miniature package and the output can be resistor trimmed from
0.59Vdc to 5.0Vdc. It provides a very cost effective, high efficiency,
and high density point of load solution. 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.
