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.

Electrical Characteristics
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage and
junction temperature range TJ from – 25° C to 125°C . Typical values represent the median values, which are
related to 25°C. If not otherwise stated, a supply voltage of VCC = 15 V is assumed for test condition.
