iW673 Datasheet | Dialog Semiconductor

i W673 Digital Green-Mode Synchronous Rectifier Controller 1.0 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 voltage up to 30V - - Optimized 5V MOSFET gate driver - - Intelligent low power management achieves ultra-low no-load operating current < 0.65m A - - Lossless MOSFET VDS sensing for SR timing control - - 6-pin SOT23 package 2.0 Description The i W673 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 i W673 can emulate the diode rectifier at the secondary side of the flyback to reduce conduction loss. The i W673 determines the timing of the driver by sensing the voltage across the RDS(ON) to...
