Delphi Series E48SH, 120W Eighth Brick Family 
DC/DC Power Modules: 48V in, 3.3V/30A out

 

 
The Delphi Series E48SH Eighth 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 either a through-hole or surface-mounted 
package and provides up to 120 watts of power or 50A of output current 
(1.2V and below) in an industry standard footprint and pinout. The E48SH 
converter operates from an input voltage of 36V to 75V and is available in
output voltages from 1.0V to 15V. Efficiency is up to 92.0% for 3.3V 
output at 30A full load. 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 fully protected
from abnormal input/output voltage, current, and temperature conditions.
The Delphi Series converters meet all safety requirements with basic 
insulation.
