TDK iFA Series manual Reliability, Quality

Advance Data Sheet: MaxetaTM iFA Series

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.
