Delphi Series S48SP, 35W 1x1 Brick
DC/DC Power Modules: 48V in, 5V/7A out
The Delphi Series S48SP, 1x1 Brick, 48V input, single output, isolated
DC/DC converters are the latest offering from a world leader in power
systems technology and manufacturing -- Delta Electronics, Inc. This
product family is available in a surface mount or through-hole package
and provides up to 35 watts of power or 10A of output current (3.3V and
below) in a new 1x1 form factor (1.3”x0.96”x0.33”). The pinout is
compatible with the industry standard 1x2 products. 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 5V/7A module is 90%. All modules
are fully protected against abnormal input/output voltage, current, and
temperature conditions.
