Delphi S48SE, 17W 1x1 Brick Series
DC/DC Power Modules: 48V in, 5A out

The Delphi S48SE series, 1x1 Brick, 48V input, single output,

isolated DC/DC converters are the latest offering from one of the

world’s largest power supply manufacturers ― Delta Electronics, Inc.

This product family is available in a surface mount or through-hole

package and provides up to 17 watts of power or 5A of output current

(3.3V and below) in a standard 1x1 form factor (1.1”x0.96”x0.33”).

The pinout is compatible with the industry standard 1x2 products.

With creative design technology and optimization of componen

placement, these converters possess outstanding electrical and

thermal performance, as well as extremely high reliability unde

highly stressful operating conditions. Typical efficiency of 3.3V/5

module is 87% and all modules are fully protected from abnormal

input/output voltage, current, and temperature conditions.
