Synchronous Rectification ICs

Increasing demands for higher power density, smaller size, more portability and more flexible systems spur the SMPS industry to continuously design new generations of AC-DC power supplies. We support our customers to meet design and performance goals through a wide portfolio of power devices including synchronous rectification ICs.

IR1161L and IR11688S - synchronous rectification controller for SMPS

Infineon’s synchronous rectification (SR) controller family IR1161L and IR11688S for switch mode power supply (SMPS) meets the new 2016 standards set forth by the U.S. DoE and EU CoC demanding higher efficiency from external power supplies. Together with Infineon’s best-in-class OptiMOS™ and StrongIRFET™, IR1161L and IR11688S are here to provide a simple way to drive the MOSFETs and therefore improve efficiency by 1 to 3% depending on output loads. IR1161L is targeting flyback SMPS especially in charger and adapter applications while IR11688S is focusing on LLC SMPS applications.
