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.

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 automated final test.

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 TDK 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.

Warranty

TDK Innoveta’s comprehensive line of power solutions includes efficient, high-density DC-DC converters. TDK Innoveta offers a three-year limited warranty. Complete warranty information is listed on our web site or is available upon request from TDK Innoveta.
