Belleta® iEA Series DC/DC Power Modules  
48V Input, 25A Output  
Eighth Brick  
The Belleta Series offers an industry standard  
eighth brick power module with true useable  
power. Thanks to its low component count and  
single-board open-frame design, it provides both  
better electrical and thermal performance, and  
lower cost than many other suppliers’ eighth brick  
product offerings. Belleta® modules are perfect  
for both next generation planning and cost  
reduction design environments

Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s  
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in  
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.  
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in  
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or  
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the  
critical component for system verification tests.

Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s  
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in  
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.  
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in  
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or  
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the  
critical component for system verification tests.

Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s  
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in  
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.  
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in  
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or  
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the  
critical component for system verification tests.

Both the thermal curves provided and the example given above are based upon measurements made in TDK Innoveta’s  
experimental test setup that is described in the Thermal Management section. Due to the large number of variables in  
system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application.  
The critical component should be thermo coupled and monitored, and should not exceed the temperature limit specified in  
the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact or  
significant measurement errors may result. TDK Innoveta can provide modules with a thermocouple pre-mounted to the  
critical component for system verification tests.

Adjacent PCB  
A finite amount of heat must be dissipated  
from the power module to the surrounding  
environment. This heat is transferred by the  
three modes of heat transfer: convection,  
conduction and radiation. While all three  
modes of heat transfer are present in every  
application, convection is the dominant  
mode of heat transfer in most applications.  
However, to ensure adequate cooling and  
proper operation, all three modes should be  
considered in a final system configuration.

Heat transfer by convection can be  
An optional latching over-voltage protection  
enhanced by increasing the airflow rate that  
the power module experiences. The  
maximum output current of the power  
module is a function of ambient temperature  
(TAMB) and airflow rate as shown in the  
thermal performance figures on the thermal  
performance page for the power module of  
interest. The curves in the figures are  
shown for natural convection through 2 m/s  
(400 ft/min). The data for the natural  
convection condition has been collected at  
0.3 m/s (60 ft/min) of airflow, which is the  
typical airflow generated by other heat  
dissipating components in many of the  
systems that these types of modules are  
used in. In the final system configurations,  
the airflow rate for the natural convection  
condition can vary due to temperature  
gradients from other heat dissipating  
components.  
is available. On modules with this feature,  
the power module will shut down once it  
detects that the output voltage has reached  
the level indicated on the Electrical Data  
section for the power module of interest.  
The module remains off unless the input  
voltage is recycled.  
Thermal Protection: When the power  
modules exceed the maximum operating  
temperature, the modules may turn off to  
safeguard the power unit against thermal  
damage. The module will auto restart as the  
unit is cooled below the over temperature  
threshold. On modules with the latching  
over-voltage protection feature, the unit may  
latch off during a severe over temperature  
condition; the module remains off unless the  
input voltage is recycled.  
Remote On/Off: - The power modules have  
an internal remote on/off circuit. The user  
must supply an open-collector or compatible  
switch between the Vin(-) pin and the on/off  
pin. The maximum voltage generated by  
the power module at the on/off terminal is  
15V. The maximum allowable leakage  
current of the switch is 50uA. The switch  
must be capable of maintaining a low signal  
Von/off < 1.2V while sinking 1mA.  
Operating Information:  
Over-Current Protection: The power  
modules have current limit protection to  
protect the module during output overload  
and short circuit conditions. During overload  
conditions, the power modules may protect  
themselves by entering a hiccup current limit  
mode. The modules will operate normally  
once the output current returns to the  
specified operating range. There is a typical  
delay of 30mS from the time an overload  
condition appears at the module output until  
the hiccup mode will occur.  
The standard on/off logic is positive logic.  
The power module will turn on if terminal 2 is  
left open and will be off if terminal 2 is  
connected to terminal 3. If the positive logic  
circuit is not being used, terminal 2 should  
be left open.  
Output Over-Voltage Protection: The  
power modules have a control circuit,  
independent of the primary control loop that  
reduces the risk of over voltage appearing at  
the output of the power module during a  
fault condition. If there is a fault in the  
primary regulation loop, the over voltage  
protection circuitry will cause the power  
module to enter a hiccup over-voltage mode  
once it detects that the output voltage has  
reached the level indicated on the Electrical  
Data section for the power module of  
interest. When the condition causing the  
over-voltage is corrected, the module will  
operate normally.  
An optional negative logic is available. The  
power module will turn on if terminal 2 is  
connected to terminal 3, and it will be off if  
terminal 2 is left open. If the negative logic  
feature is not being used, terminal 2 should  
be shorted to terminal 3.

from the power module is fixed. As the  
output voltage is trimmed up, the maximum  
output current must be decreased to  
maintain the maximum rated power of the  
module. As the output voltage is trimmed,

Remote Sense: The power modules feature  
remote sense to compensate for the effect  
of output distribution drops. The output  
voltage sense range defines the maximum  
voltage allowed between the output power  
terminals and output sense terminals, and it  
is found on the electrical data page for the  
power module of interest. If the remote  
sense feature is not being used, the  
Sense(+) terminal should be connected to  
the Vo(+) terminal and the Sense (-)  
terminal should be connected to the Vo(-)  
terminal.  
Input Impedance:  
The source impedance of the power feeding  
the DC/DC converter module will interact  
with the DC/DC converter. To minimize the  
interaction, a 10-100uF input electrolytic  
capacitor should be present if the source  
inductance is greater than 1.5uH.  
Reliability:  
The power modules are designed using TDK  
Innoveta’s stringent design guidelines for  
component derating, product qualification,  
and design reviews. Early failures are  
screened out by both burn-in and an  
automated final test. The MTBF is  
calculated to be greater than 4.8M hours at  
full output power and Ta = 40˚C using the  
Telcordia SR-332 calculation method.  
The output voltage at the Vo(+) and Vo(-)  
terminals can be increased by either the  
remote sense or the output voltage  
adjustment feature. The maximum voltage  
increase allowed is the larger of the remote  
sense range or the output voltage  
adjustment range; it is not the sum of both.  
Improper handling or cleaning processes  
can adversely affect the appearance,  
testability, and reliability of the power  
modules. Contact TDK Innoveta technical  
support for guidance regarding proper  
handling, cleaning, and soldering of TDK  
Innoveta’s power modules.  
As the output voltage increases due to the  
use of the remote sense, the maximum  
output current must be decreased for the  
power module to remain below its maximum  
power rating.  
EMC Considerations: TDK Innoveta power  
modules are designed for use in a wide  
variety of systems and applications. For

process incorporates advanced quality  
planning tools such as FMEA and Cpk  
analysis to ensure designs are robust and  
reliable. All products are assembled at ISO  
certified assembly plants.

The input reflected ripple is measured with a current probe and oscilloscope. The ripple  
current is the current through the 12uH inductor.  
The output ripple measurement is made approximately 9 cm (3.5 in.) from the power module  
using an oscilloscope and BNC socket. The capacitor Cext is located about 5 cm (2 in.) from  
the power module; its value varies from code to code and is found on the electrical data page  
for the power module of interest under the ripple & noise voltage specification in the Notes &  
Conditions column.  
Safety Considerations:

For safety agency approval of the system in  
which the DC-DC power module is installed,  
the power module must be installed in  
compliance with the creepage and clearance  
requirements of the safety agency. The  
isolation is basic insulation. For  
less than 60Vdc, the power module meets  
all of the requirements for SELV. If the  
input voltage is a hazardous voltage that  
exceeds 60Vdc, the output can be  
considered SELV only if the following  
conditions are met:  
applications requiring basic insulation, care  
must be taken to maintain minimum  
creepage and clearance distances when  
routing traces near the power module.  
1) The input source is isolated from the  
ac mains by reinforced insulation.  
2) The input terminal pins are not  
accessible.  
3) One pole of the input and one pole  
of the output are grounded or both  
are kept floating.  
4) Single fault testing is performed on  
the end system to ensure that under  
a single fault, hazardous voltages  
do not appear at the module output.  
As part of the production process, the power  
modules are hi-pot tested from primary and  
secondary at a test voltage of 1500Vdc.  
To preserve maximum flexibility, the power  
modules are not internally fused. An  
external input line normal blow fuse with a  
maximum value of 10A is required by safety  
agencies. A lower value fuse can be  
selected based upon the maximum dc input  
current and maximum inrush energy of the  
power module.
