Is Now Part of 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 Semiconductors 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.

The FAN6982 includes circuits for the implementation of leading edge, average Average-Current-Mode for Input-Current Shaping current, boost-type power factor correction, and TriFault Detect Prevent Abnormal Operation for results in a power supply that fully complies with the Feedback Loop IEC1000-3-2 specification. Power-On Sequence Control A TriFault Detect function helps reduce external components and provides full protection for feedback Soft-Start Capability loops such as open, short, and over voltage. An over- Brownout Protection voltage comparator shuts down the PFC stage in the event of a sudden load decrease. The RDY signal can Cycle-by-Cycle Peak Current Limiting. be used for power-on sequence control. The EN Improves Light-Load Efficiency function can choose to enable or disable the range function. FAN6982 also includes PFC soft-start, peak Fulfills Class-D Requirements of IEC 1000-3-2 current limiting, and input voltage brownout protection.
