The critical component hould be thermo coupled and monitored, and hould not exceed the temperature limit pecified in
the derating curve above. It i critical that the thermocouple be mounted in a manner that give direct thermal contact or

Wind Tunnel Test Setup Figure Dimen ion are
in millimeter and (inche ).
Thermal Management:
An important part of the overall y tem
de ign proce i thermal management;
thermal de ign mu t be con idered at all
level to en ure good reliability and lifetime
of the final y tem. Superior thermal de ign
and the ability to operate in evere
application environment are key element
of a robu t, reliable power module.
A finite amount of heat mu t be di ipated
from the power module to the urrounding
environment. Thi heat i tran ferred by the
three mode of heat tran fer: convection,
conduction and radiation. While all three
mode of heat tran fer are pre ent in every
application, convection i the dominant mode
of heat tran fer in mo t application .
However, to en ure adequate cooling and
proper operation, all three mode hould be
con idered in a final y tem configuration.
The open frame de ign of the power module
provide an air path to individual
component . Thi air path improve
convection cooling to the urrounding
environment, which reduce area of heat
concentration and re ulting hot pot .
Test Setup: The thermal performance data
of the power module i ba ed upon
mea urement obtained from a wind tunnel
te t with the etup hown in the wind tunnel
figure. Thi thermal te t etup replicate the
typical thermal environment encountered in
mo t modern electronic y tem with
di tributed power architecture . The
electronic equipment in networking, telecom,
wirele , and advanced computer y tem
operate in imilar environment and utilize
vertically mounted PCB or circuit card in
cabinet rack .
The power module, a hown in the figure, i
mounted on a printed circuit board (PCB)
and i vertically oriented within the wind
tunnel. The cro ection of the airflow
pa age i rectangular. The pacing
between the top of the module and a parallel
facing PCB i kept at a con tant (0.5 in).
The power module’ orientation with re pect
to the airflow direction can have a ignificant
impact on the module’ thermal
performance.
Thermal Derating: For proper application of
the power module in a given thermal
environment, output current derating curve
are provided a a de ign
guideline on the Thermal Performance
ection for the power module of intere t.
The module temperature hould be
mea ured in the final y tem configuration to
en ure proper thermal management of the
power module. For thermal performance
verification, the module temperature hould
be mea ured at the component indicated in
the thermal mea urement location figure on
the thermal performance page for the power
module of intere t. In all condition , the
power module hould be operated below the
maximum operating temperature hown on
the derating curve. For improved de ign
margin and enhanced y tem reliability, the
power module may be operated at
temperature below the maximum rated
operating temperature.

Heat tran fer by convection can be
enhanced by increa ing the airflow rate that
the power module experience . The
maximum output current of the power
module i a function of ambient temperature
(T
AMB
) and airflow rate a hown in the
thermal performance figure on the thermal
performance page for the power module of
intere t. The curve in the figure are hown
for natural convection through 2 m/ (400
ft/min). The data for the natural convection
condition ha been collected at 0.3 m/ (60
ft/min) of airflow, which i the typical airflow
generated by other heat di ipating
component in many of the y tem that
the e type of module are u ed in. In the
final y tem configuration , the airflow rate
for the natural convection condition can vary
due to temperature gradient from other heat
di ipating component .
Operating nformation:
Over-Current Protection: The power
module have current limit protection to
protect the module during output overload
and hort circuit condition . During overload
condition , the power module may protect
them elve by entering a hiccup current limit
mode. The module will operate normally
once the output current return to the
pecified operating range
Thermal Protection: When the power
module exceed the maximum operating
temperature, the module may turn off to
afeguard the power unit again t thermal
damage. The module will auto re tart a the
unit i cooled below the over temperature
thre hold.
Remote On/Off: - The power module have
an internal remote on/off circuit. The u er
mu t upply an open-collector or compatible
witch between the Vin(-) pin and the on/off
pin. The maximum voltage generated by
the power module at the on/off terminal i
15V. The maximum allowable leakage
current of the witch i 50uA. The witch
mu t be capable of maintaining a low ignal
Von/off < 1.2V while inking 1mA.
The tandard on/off logic i po itive logic.
The power module will turn on if terminal 2 i
left open and will be off if terminal 2 i
connected to terminal 3. If the po itive logic
circuit i not being u ed, terminal 2 hould
be left open.
An optional negative logic i available. The
power module will turn on if terminal 2 i
connected to terminal 3, and it will be off if
terminal 2 i left open. If the negative logic
feature i not being u ed, terminal 2 hould

compliance, plea e contact TDK Innoveta
technical upport.
nput mpedance:
The ource impedance of the power feeding
the DC/DC converter module will interact

Safety Considerations:
Check with TDK Innoveta for the current
tatu of afety approval on the iEB product
family.
For afety agency approval of the y tem in
which the DC-DC power module i in talled,
the power module mu t be in talled in
compliance with the creepage and clearance
requirement of the afety agency. The
i olation i ba ic in ulation. For
application requiring ba ic in ulation, care
mu t be taken to maintain minimum
creepage and clearance di tance when
routing trace near the power module.
A part of the production proce , the power
module are hi-pot te ted from primary and
econdary at a te t voltage of 1500Vdc.
To pre erve maximum flexibility, the power
module are not internally fu ed. An
external input line normal blow fu e with a
maximum value of 10A i required by afety
agencie . A lower value fu e can be
elected ba ed upon the maximum dc input
current and maximum inru h energy of the
power module.
When the upply to the DC-DC converter i
le than 60Vdc, the power module meet
all of the requirement for SELV. If the
input voltage i a hazardou voltage that
exceed 60Vdc, the output can be
con idered SELV only if the following
condition are met:
1) The input ource i i olated from the
ac main by reinforced in ulation.
2) The input terminal pin are not
acce ible.
3) One pole of the input and one pole
of the output are grounded or both
are kept floating.
4) Single fault te ting i performed on
the end y tem to en ure that under
a ingle fault, hazardou voltage
do not appear at the module output.
