Winsemi WS2994

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. The WS2994 is Green, when the load current reduce to a certain level, the gate drive is turned off, thus limiting the IC current to less than 140uA.

DESCRIPTION

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. The fast shutdown capability of the WS2994 supports continuous conduction mode (CCM) and discontinuous conduction mode (DCM) operation. It is highly-integrated with SOP8 package.
