DC/DC Power Modules: 48V in, 15V, 4.4A out
The Delphi Series V48SR, 1/16
th
Brick, 48V input, single output, isolated
DC/DC converter, is the latest offering from a world leader in powe
r
systems technology and manufacturing Delta Electronics, Inc. This
product family provides up to 66 watts of power or 25A of output curren
t
(1.8V and below) in an industry standard 1/16
th
brick form factor (1.30”
x
0.90”). The 15V output offers one of the highest output currents available
and provides up to 90.5% efficiency at full load. 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
modules are protected from abnormal input/output voltage, current, and
temperature conditions. For lower power needs with the 15V output, bu
t
in a similar small form factor, please check out Delta S48SP (36W o
r
15V/2.3A) and S48SE (17W or 15V/1A) series standard DC/DC modules.
