Advance Data Sheet: FReta iEB Series –Single Output Eighth Brick Bus Converter

EMC Considerations: TDK Innoveta power modules are designed for use in a wide variety of systems and applications. For assistance with designing for EMC compliance, please contact TDK Innoveta technical support.

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 33-100uF input electrolytic capacitor should be present if the source inductance is greater than 2uH.

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

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.
