Manager Quality & Reliability Dept. Engineer Conclusion: The AME7739 SOT-26 series product has successfully met AME’s reliability standard that is required on all AME, Inc products. Furthermore, QRA Dept. of AME, Inc monitors the reliability continuously to make sure that all AME7739 SOT-26 series product will still meet AME’s reliability standard in the future. Table of Contents I、General Description II、Product Information III、Failures In Time Calculation IV、Product Reliability Test Result V、Package Reliability Test Result VI、IR-reflow Test Result I、General Description: The AME7739 is a charge pump voltage converter that delivers a regulated output. No external inductor is required for operation. Using three small capacitors, the AME7739 can deliver up to 60mA to the voltage regulated output. The AME7739 features very low output ripple and high efficiency over a large portion of its load range making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keep the total converter board area to a minimum in space restricted applications. The AME7739 contains a thermal management circuit to protect the device under continuous output short circuit conditions. The AME7739 is available in SOT-26 package and is rated from -40OC to +85OC. II、Product Information: III、Failures In Time Calculation: Use HTOL test information mentioned in sectionⅣ, FIT (Failures In Time) can be calculated as below: FIT = ( x 2 (ν , CL ) × 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 ) =106.69 (pieces per 109 hours) @ 40℃ with 90% Confidence Level. Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
