    产品信息

    The FAN6248 is an advanced synchronous rectifier (SR) controller that is optimized for LLC resonant converter topology with minimum external components. It has two driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own sensing inputs and operate independently of each other. The adaptive parasitic inductance compensation function minimizes the body diode conduction maximizing the efficiency. The advanced control algorithm allows stable SR operation over entire load range. FAN6248 has two different versions - FAN6248HAMX having higher turn-off threshold voltage and FAN6248HBMX having lower turn-off threshold voltage.
    • Highly integrated self-contained control of synchronous rectifier with a minimum external component count
    • Optimized for LLC resonant converter
    • Anti shoot-through control for reliable SR operation
    • Separate 100V rated sense inputs for sensing the drain and source voltage of each SR MOSFET
    • Adaptive parasitic inductance compensation to minimize the body diode conduction
    • SR current inversion detection under light load condition
    • Light load detection
    • Adaptive minimum on time for noise immunity
    • Operating voltage range up to 30 V
    • Low start-up and stand-by current consumption
    • Operating frequency range from 25kHz up to 700 kHz
    • High driver output voltage of 10.5 V to drive all MOSFET brands to the lowest RDS_ON
    • Low operating current in green mode (typ. 350uA)
