Delphi Series S48SS, 15W Family DC/DC Power Modules: 48V in, 4.5A out

The Delphi Series S48SS, 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 15 watts of power or up to 4.5A o

output current (for 3.3V and below) in an industry standard footprint.

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. An encapsulated version is

available for the most robust performance in harsh environments.
