Auxiliary Bias Power (Optional):
The iFA
series power modules provide an auxiliary
output, which is referenced to the output
sense (-) pin. It provides an output voltage
between 7.5 and 13.5Vdc that can supply a
maximum current of 20mA. The auxiliary
bias circuitry does not have short circuit
protection and may be damaged if over
loaded. An internal diode in series with the
AUX output pin is provided to protect against
reverse voltage up to 75V.
External Synchronization (Optional):
An
optional feature is available for the iFA
series, allowing the power module(s) to be
synchronized with an external clock
synchronization input from an independent
time base. Contact Innoveta for more details
on the external clock synchronization
feature.
EMC Considerations:
Innoveta DC/DC
converter modules are designed for use in a
wide variety of systems and applications.
With the help of external filters and careful
layout, it is possible to meet CISPR 22 Class
B. For assistance with designing for EMC
compliance, please contact Innoveta
technical support.
Input Impedance: The source impedance
of the input power feeding the DC/DC
converter module will interact with the
DC/DC converter, which may cause system
instability. To minimize the interaction, two
or more 470µF / 50V input electrolytic
capacitor(s) should be present if the source
inductance is greater than 4µH.
Reliability:
The power modules are designed using
Innoveta’s stringent design guidelines for
component de-rating, 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 1.5M hours at nominal
input, 100% output power, 0.5” heatsink,
200LFM airflow, and Ta = 40˚C using the
Telcordia TR-332 issue 6 calculation
method.
Improper handling or cleaning processes
can adversely affect the appearance,
testability, and reliability of the power
modules. Contact Innoveta technical
support for guidance regarding proper
handling, cleaning, and soldering of
Innoveta’s power modules.
Quality:
TDK Innoveta’s product development
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.
