Delphi Series E24SR, 66W Eighth Brick Family
DC/DC Power Modules: 24V in, 3.3V/20A outwww.DataSheet4U.com
The Delphi Series E24SR Eighth Brick, 24V 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 66 watts of power or 20A of output current
(3.3V and below) in an industry standard footprint and pinout. The
E24SR converter operates from an input voltage of 18V to 36V and is
available in output voltages from 3.3V to 12V. Efficiency for the 3.3V
output is 90% at 20A 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 8: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (100mV/div, 200us/div), Bottom Trace: Iout (5A/div).
Scope measurement 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
Figure 9: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 2.5A/µs). Load cap:
470µF, 35mΩ ESR solid electrolytic capacitor and 1µF ceramic
capacitor. Top Trace: Vout (100mV/div, 200us/div), Bottom
Trace: Iout (5A/div). Scope measurement 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

Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (LTEST) of 12 µH. Capacitor Cs offset
possible battery impedance. Measure current as shown above
