iW671 Overview
The iW671 is a high performance synchronous rectifier controller with an integrated MOSFET driver for flyback converters operating at discontinuous conduction mode. bined with the MOSFET, the iW671 can emulate the diode rectifier at the secondary side of the flyback to reduce conduction loss. The iW671 determines the timing of the driver by sensing the voltage across the RDS(ON) to achieve lossless sensing.
