The Delphi D12S1R880D, surface mounted, power block is the
latest offering from a world leader in power systems technology and
manufacturing — Delta Electronics, Inc. The D12S1R880D is the
latest offering in the DXP80 family which was developed to address
the ever-growing demands of increased current and power densities
in networking applications while providing maximum flexibility for
system configuration, its benefits can easily be applied to other
applications transcending various market segments. The DXP80
family, containing all necessary power components and boasting of
a USABLE (55˚C, 200LFM) current density of 160A/in2 and a power
density of up to 890W/in3, is a building block for a new open Digital
Power Architecture developed to work with either digital or analog
controllers. Measured at 0.5”Wx1.0”Lx0.48”H and rated at 80A of
output current, the D12S1R880D is designed to operate with an
input voltage from 7V to 13.2V and provide an output voltage
adjustable from 0.6V to 3.3V. Each D12S1R880D contains two
power trains which can provides either an interleaved single output,
or two independent outputs. Multiple D12S1R880D can be used in
parallel to serve applications where output currents are in excess of
80A with limitation imposed only by the control circuit, analog or
digital. Designed for superior price/performance, the D12S1R880D
can provide 1.8V and 80A full load in ambient temperature up to
55˚C with 200LFM airflow.

TEST CONFIGURATIONS
DESIGN CONSIDERATIONS
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the module. An
input capacitance must be placed close to the modules
input pins to filter ripple current and ensure module
stability in the presence of inductive traces that supply the
input voltage to the module.

FEATURES DESCRIPTIONS

Over-Current Protection
Note: 6pcs 330μF TAN and 2 pcs 100μF MLCC
capacitor in the module output. Scope measurement
should be made by using a BNC connector.

LOAD
SUPPLY
To provide protection in an output over load fault
condition, the unit is equipped with over-current
protection by external controller. When the over-current
protection is triggered, the unit will be shutdown and
restart after a period of time. The units operate normally
once the fault condition is removed.

Over-Temperature Protection
CONTACT RESISTANCE
The over-temperature protection was provided by the
external circuitry or controller ，it can protect our module

from thermal damage. If the temperature exceeds the
over-temperature threshold the module will shut down.
Note: All measurements are taken at the module
terminals. When the module is not soldered (via socket),
place Kelvin connections at module terminals to avoid
measurement errors due to contact resistance.

THERMAL CONSIDERATIONS
THERMAL CURVES
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.
Figure 25: * Hot spot temperature measured point.
The allowed maximum hot spot temperature is defined at 115℃.
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.
Figure 24: Wind tunnel test setup
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.
