Delphi Series V48SR, 1/16
th
Brick 66W
DC/DC Power Modules: 48V in, 1.2V~15V, 25A out
The Delphi Series V48SR, 1/16th 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 a new 1/16th brick form factor (1.3”x0.90”) and pinout.
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. Typical efficiency of the 3.3V/20A module is greater than
90.5%. All modules are protected from abnormal input/output voltage,
current, and temperature conditions. For lower power needs, but in a
similar small form factor, please check out Delta S48SP (36W or 10A) and
S48SE (17W or 5A) series standard DC/DC modules.
