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 FAN6240M6X is a secondary-side synchronous rectifier (SR) controller for an isolated flyback converter Adaptive Turn-off Trigger Blanking Time for easier operating in Discontinuous Conduction Mode (DCM). use The adaptive dead-time control algorithm minimizes the Turn-on Trigger Blanking Time (Minimum-OFF body diode conduction of SR MOSFET while guaranteeing stable and robust SR operation against Time) for Improved Noise Immunity noise and disturbance caused by the circuit parasitic. Supports High-Frequency Applications up to 30 V rated input voltage LDO and Low VDD Under- 200 kHz Voltage Lockout (UVLO) voltage allow FAN6240M6X to be used for wide ranges of switched mode power supply Minimum Turn-on Delay (20 ns) output voltage without additional circuit. Adaptive Turn-off Threshold Control for Minimized SR MOSFET Body Diode Conduction (Dead-Time Applications is independent of SR MOSFET) Battery Chargers for Smart Phones, Feature Wide Voltage Range for LDO Input up to 30 V Phones, and Tablet PCs Small Footprint: SOT-23 6 Pin Package AC-DC Adapters for Portable Devices that Require CV/CC Control Ordering Information Operating Packing Part Number Package Temperature Range Method 6-Lead, SOT23, JEDEC MO-178 Variation AB, FAN6240M6X -40 C to +125 C Tape & Reel 1.6 mm Wide 2016 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN6240 Rev. 1.0
