Auxiliary Bias Power:
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, one
or more 100 - 470µF input electrolytic
capacitor(s) should be present if the source
inductance is greater than 4µH.
Reliability:
The power modules are designed using TDK
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 MTTF is calculated
to be greater than 0.67M hours at nominal
input, 80% output power, 0.5” heatsink,
200LFM airflow, and Tc = 80˚C using the
Telcordia TR-332 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.
