General 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.
