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
t
placement, these converters possess outstanding electrical and
thermal performance, as well as extremely high reliability unde
r
highly stressful operating conditions. Typical efficiency of 3.3V/5
A
module is 87% and all modules are fully protected from abnormal
input/output voltage, current, and temperature conditions.
