WS2994 Datasheet WS2994 Fast turn-off Dual LLC Synchronous Rectifier Controller Description WS2994 is a high performance dual channel synchronous rectifier controller, which is applied to the output side rectifier of half bridge LLC resonant converter, and can realize the optimal control of MOSFET. By detecting the Vds voltage of the rectified MOSFET, the MOSFET can be reliably switched on and off, thereby replacing Schottky diodes and improving the efficiency of the half-bridge LLC converter. WS2994 Gate voltage can be regulated according to output load with different turn-on delay time,avoiding false turn-on because of capacitive current during light load.
