COMPUTING / CONSUMER / GAMES THE POWER MANAGEMENT LEADER SmartRectifier™ IR1167: Simple, High Efficiency Synchronous Rectification IR Advantage: • Simple, powerful solution • Enables – Higher efficiency – Higher power density – Faster time to market • Complies with CEC 80plus and 1W standby requirements • Proprietary “Voltage Level Detection” and 200V HVIC technology • Direct connection and drive to all 30-200V MOSFETs • Fast, powerful (7A), accurate, high efficiency operation up to 500kHz • Independent from primary side • Operates in all modes (CCM, CRCM, DCM) • In 120W laptop adaptor, enables – 1% efficiency increase – 10˚C lower temperature – 75% fewer SR components – 20% lower SR system cost • Enables ‘no heatsink’ SR designs For designers of high power flyback and resonant half-bridge converters for Lap- tops, Mini-PCs, LCD & 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 IR1167 is a secondary control IC with builtin 7A gate drive. Operating independently from the primary side, it uses a proprietary “Voltage Level Detection” technique to minimize wasteful secondary reactive currents and maximize 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.
