LED Driver Lifetime and Reliability

Download Whitepaper
This document also describes the strict design procedure followed for the development of Xitanium LED drivers to ensure high lifetime and reliability. The design and development of all Xitanium LED drivers pass through a tightly controlled process. The quality of product is critically evaluated at each milestone and activities to realize deliverables (and guidelines on how to perform such activities) are clearly defined. All field return issues are carefully documented and all failure issues are reviewed at the start of each new project so that the learnings can be carried forward to new designs. This feedback and improvement cycle has been part of the Philips product development process for over a decade, resulting in products which perform far better than the theoretical estimates
