FAN6248HC/HD/LC/LD  
Advanced Synchronous  
Rectifier Controller for LLC  
Resonant Converter  
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.  
According to the operating frequency and turn-off threshold voltage,  
FAN6248 has four different versions − FAN6248HCMX,  
FAN6248HDMX, FAN6248LCMX, FAN6248LDMX.
