Delphi Series E48SH, 120W Eighth Brick Family
www.DataSheet4U.com
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.

Figure 12: Input reflected ripple current, is, through a 12µH
source inductor at nominal input voltage and rated load current
(20 mA/div, 2us/div).

rated load current (Io=30A)(50 mV/div, 2us/div)
Load capacitance: 1µF ceramic capacitor and 10µF tantalum
capacitor. Bandwidth: 20 MHz. Scope measurements 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.
