To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description

This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides features to enhance the performance of LED illumination. The proprietary topology, TRUECURRENT ®, enables precise CC regulation and simplified circuit for LE D illumination applications. The result is l ower-cost and smaller LED lighting compared to a conventional design or a linear transformer. To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease PWM frequency with cycle skipping under light-load conditions. Green mode assists the power supply in meeting the power conservation requirements. By using the FL663, LED illumination can be implemented with few external components and minimized cost.
