IR11682S
Description
IR11682 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
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. The anti shoot-through logic prevents both channels from
turning on the power switches at the same time. The cycle-by-cycle MOT protection circuit can automatically
detect no load condition and turn off gate driver output to avoid negative current flowing through the
MOSFETs. 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.
