IR1168S
Description
IR1168 is dual smart secondary-side rectifier driver IC designed to drive two N-Channel power MOSFETs used as
synchronous rectifiers in resonant converter applications. The IC can control one or more paralleled N MOSFETs
to emulate the behavior of Schottky diode rectifiers. The drain to source for each rectifier MOSFET voltage is
sensed differentially to determine the level of the current and the power switch is turned ON and OFF in close
proximity of the zero current transition. Ruggedness and noise immunity are accomplished using an advanced
blanking scheme and double-pulse suppression that allows reliable operation in fixed and variable frequency
applications.
