The Delphi D12S1R830, surface mounted, power block is the latest offering
from a world leader in power systems technology and manufacturing —
Delta Electronics, Inc. The D12S1R830 is the latest offering in the DXP30
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
DXP30 family, containing all necessary power components and boasting of
2
a USABLE (55˚C, 200LFM) current density of 60A/in and a power density
3
of up to 216W/in , 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 30A of output current, the
D12S1R830 is designed to operate with an input voltage from 7V to 13.2V
and provide an output voltage adjustable from 0.8V to 1.8V in digitally
defined step resolution of 1.62mV. Multiple D12S1R830 can be used in
parallel to serve applications where output currents are in excess of 30A
with limitation imposed only by the control circuit, analog or digital. Designed
for superior price/performance, the D12S1R830 can provide 1.8V and 30A
full load in ambient temperature up to 55˚C with 200LFM airflow.

DESIGN CONSIDERATIONS
TEST CONFIGURATIONS

560uF*3 320uF
SCOPE
Load
Oscon MLCC
GND
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.
Safety Considerations
Figure 11: Peak-peak output ripple & noise and startup
transient measurement test setup
Note: 3pcs 560µF OSCON and 320µF MLCC capacitor
in the module output. Scope measurement should be
made by using a BNC connector.

For safety-agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power module
has extra-low voltage (ELV) outputs when all inputs are
ELV.
The input to these units is to be provided with a
maximum 15A time-delay fuse in the ungrounded lead.

To provide protection in an output over load fault
condition, the unit is equipped with internal over-current
protection. When the over-current protection is
triggered, the unit will be shutdown and restart by input
or OUTEN on/off. The units operate normally once the
fault condition is removed.
Over-Temperature Protection
Vo
To provide additional over-temperature protection in a
fault condition, the unit is equipped with a latching thermal
shutdown circuit. The shutdown circuit engages when the
temperature
of
monitored
component
exceeds
approximately 130℃. The shutdown unit will restart by
input or OUTEN on/off while the temperature lower than
125C.

THERMAL CONSIDERATIONS
Thermal De-rating
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.
The module’s maximum hot spot temperature is +113°C.
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.
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 wind tunnels that simulate the thermal
environments encountered in most electronics
equipment.
The following figures show the wind tunnel
characterization setup. The power module is mounted
on Primarion test board and is horizontally positioned
within the wind tunnel.
