Delphi Series S48SA, 33W Family
DC/DC Power Modules: 48V in, 1.2V/12A out
The Delphi Series S48SA, surface mountable, 48V input, single
output, isolated DC/DC converters are the latest offering from a
world leader in power system and technology and manufacturing –
Delta Electronics, Inc. This product family provides up to 33 watts
of power or up to 12A of output current (1.8V or below). 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 are protected from
abnormal input/output voltage and current conditions.

Figure 9: Input Reflected Ripple Current, is, at full rated output
current and nominal input voltage with 12µH source impedance
and 33µF electrolytic capacitor (2 mA/div).
Figure 10: Output voltage noise and ripple measurement test
setup. Scope measurement should be made using a BNC
cable (length shorter than 20 inches). Position the load
between 51 mm to 76 mm (2 inches to 3 inches) from the
module.
