iW671 - Digital Green-Mode Synchronous Rectifier Controller

Description

The iW671 is a high performance synchronous rectifier controller with an integrated MOSFET driver for flyback converters operating at discontinuous conduction mode.

Features

  • Digital adaptive turn-off control minimizes deadtime and eliminates the schottky diode.
  • Integrated pulse linear regulator (PLR) allows SR operation at low system output voltage down to 2V in typical 5V2.5A USB charger.
