FAN6241M6X

FAN6241M6X Secondary Side Synchronous Rectifier Controller for Flyback Converters Description The FAN6241M6X 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 components. The 26 V rated input voltage LDO and Low VDD Under−Voltage Lockout (UVLO) voltage allow FAN6241M6X to be used for wide ranges of switched mode power supply output voltage without additional circuit. Features Support Discontinuous Conduction Modes (DCM) and Boundary Conduction Mode (BCM) Adaptive Turn−off Dead Time Tuning for General SR MOSFET Application 120 V of Voltage Rating on the Drain Pin Charge Pump (CP) Function which Enhance SR MOSFET Voltage Driving Level through Connected a Ceramic Capacitor between Gate and CP Pin Short Turn−on Delay (20 ns) Supporting PD General Output Voltage (VIN) Range: 3.25 V~25 V with LDO Input Fewest External Component Allowed At Green mode SR Driving Signal is Still Working under Extremely Low Power Consumption Small Footprint: SOT−23 6 pin These Device is Pb−Free and is RoHS Compliant Typical Applications Travel Adapter for Smart Phones, Feature Phones, and Tablet PCs AC−DC Adapters for Portable Devices that Require CV/CC Control IoT Power Applications5tt ...
