International Rectifier IR1169 Advanced
SmartRectifier Control IC
International Rectifier's IR1169 Advanced SmartRectifier™ Control IC is a high speed synchronous rectifier (SR) controller for flyback, forward and half-bridge converters used in AC-DC adapter, PC, server and Telecom SMPS applications. The IR1169 features a SYNC function that turns off the SR MOSFET to prevent reverse current flow under continuous conduction mode (CCM) operation, thereby improving functionality and reliability. Unlike existing solutions, the advanced new device uses direct sensing with capacitor coupling to help simplify design and reduce overall system cost.
