Description

Package

IR1168 is a 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 is 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.
