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