IR11662S
Description
IR11662 is a smart secondary-side driver IC designed to drive N-Channel power MOSFETs used as
synchronous rectifiers in isolated Flyback and resonant half-bridge converters. The IC can control one or
more paralleled N-MOSFETs to emulate the behavior of Schottky diode rectifiers. The drain to source voltage
is sensed differentially to determine the polarity of the current and turn the power switch on and off in
proximity of the zero current transition. 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 which allow reliable operation in all operating modes.
