Description
IR1166S is a smart secondary side driver IC designed to drive N-Channel power MOSFETs
used as synchronous rectifiers in isolated Flyback 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 transi-
tion.
Ruggedness and noise immunity are accomplished using an advanced blanking scheme
and double-pulse suppression which allow reliable operation in continuous, discontinuous
and critical current mode operation and both fixed and variable frequency modes.
