iW673 Overview
The iW673 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 iW673 can emulate the diode rectifier at the secondary side of the flyback to reduce conduction loss. The iW673 determines the timing of the driver by sensing the voltage across the RDS(ON) to ach.
iW673 Key Features
- Digital adaptive turn-off control minimizes dead-time and eliminates the parallel Schottky diode
- Integrated pulse linear regulator (PLR) allows SR operation at low system output voltage down to 2V in typical 5V, 2.5A
iW673 Applications
- Wide input operating voltage up to 30V
