iW673 Datasheet (Dialog Semiconductor) - Digital Green-Mode Synchronous Rectifier Controller

iW673, Digital Green-Mode Synchronous Rectifier Controller

The iW673 is a high performance synchronous rectifier controller with an integrated MOSFET driver for flyback converters operating at discontinuous conduction mode.

Combined with the MOSFET, the iW673 can emulate the diode rectifier at the secondary side of the flyback to reduce conduction loss.

The

iW673 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 USB charger applications

* Wide input operating volt
