Delphi Series E36SR, 75W Eighth Brick Family
DC/DC Power Modules: 18~75V in, 5V/15A out
The Delphi Series E36SR Eighth Brick, 18~75V input, single output,
isolated DC/DC converter is the latest offering from a world leader in
power systems technology and manufacturing — Delta Electronics, Inc.
This product family operates from an extremely wide 18~75V input range
and provides up to 75 watts of power in an industry standard eighth brick
footprint and pinout. With creative design technology and optimization of
component placement, these converters possess outstanding electrical
and thermal performances, 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.

Page 7: Design Considerations
DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. If the source inductance is more than a few μH, we advise adding a 10 to 100 μF electrolytic capacitor (ESR <... -
Page 8: Features Descriptions
FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automatically shut down (hiccup mode). The modules will try to restart after shutdown. - Page 9 FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-). The TRIM pin should be left open if this feature is not used.

Page 10: Thermal Considerations
THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. - Page 11 PICK AND PLACE LOCATION SURFACE-MOUNT TAPE & REEL RECOMMENDED PAD LAYOUT (SMD) DS_E36SR05015_01042008...
