Delphi Series L36SA, 2 x 1.6, 50W Family
DC/DC Power Module: 18~75V in, 12V/4A outwww.DataSheet4U.com
The Delphi Series L36SA, 2” x 1.6”, 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
L36SA series provides up to 50 watts of power or 15A of output current
(3.3V) in an industry standard 2” x 1.6” form factor and pinout. The Delphi
L36SA series operates from a wide 18~75V (4:1) input voltages. 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. An
optional heat spreader is available for extended operation.

ELECTRICAL CHARACTERISTICS CURVES
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,500us/div), Bottom Trace: I out (2A/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..

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.
Thermal Testing Setup
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
The following figure shows the wind tunnel
characterization setup. The power module is mounted
on a test PWB and is vertically positioned within the
wind tunnel. The space between the neighboring PWB
and the top of the power module is constantly kept at
6.35mm (0.25’’).

Thermal Derating
Heat can be removed by increasing airflow over the module.
To enhance system reliability, the power module should
always be operated below the maximum operating
temperature. If the temperature exceeds the maximum
module temperature, reliability of the unit may be affected.
