LP3520

LP3520 Second-Side Synchronous Rectifier Description The LP3520 is a high performance second side synchronous rectifier for isolated flyback application in which a synchronous power MOSFET is integrated. The LP3520 is suitable for charger application which the high transfer efficiency is required. The LP3520 can avoid mis-operation caused by the demagnetization oscillation efficiently by using proprietary primary side turn on estimation and secondary side current discontinuous judgment technology. LP3520 also involves proprietary VCC supply technology which can ensure the IC can work normally in primary side CC and CV working mode. The LP3520 provides many protections which include VCC UVLO, VCC over voltage clamping , output short max on time shunt down and the DRV pin interference suppression. The LP3520 is available in SOP7 Features  Isolated DCM mode application.  45V Power MOSFET integrated  Proprietary Primary Side Turn On Estimation  Secondary Side Current Disconti...
