SmartRectifier™ IR1166/67: Simple, High Efficiency Synch Rec

For designers of high power flyback and resonant 1/2 bridge converters for laptops, mini-PCs, LCD and PDP TVs and games SMPS, the SmartRectifier™ offers a simple, high efficiency solution for secondary synchronous rectification (SR) in all operational modes and application conditions.

The IR1166/67 is a secondary control IC with built-in 7A gate drive. Operating independently from the primary side, it uses a proprietary ‘Voltage Level Detection’ technique to minimize wasteful secondary reactive currents to maximize secondary efficiency.

The proprietary 200V HVIC technology allows direct sensing and control of IR’s world-class range of Standard- or Logic-Level, 30-200V HEXFET MOSFETs.
