Questions answered in these manuals
What is the function of the SRK2000 IC?
It switches on each synchronous rectifier MOSFET when the transformer half-winding starts conducting and switches it off when the current approaches zero.
How many configurations are available for the EVLSRK2000 demonstration boards?
The boards are realized in four different configurations depending on the mounted SR MOSFETs.
What is the main function of the SRK2000 in this design?
The SRK2000 is an SR driver dedicated to LLC resonant topology that controls the SR MOSFETs on the secondary side.
How does the design achieve low standby consumption?
Low standby consumption is achieved thanks to the sleep function embedded in the SRK2000 and the high voltage start-up circuit integrated in the L6563H.
