IR3558 Datasheet (International Rectifier)

IR3558, 45A Integrated PowIRstage

The IR3558 integrated PowIRstage® is a synchronous buck gate driver co-packed with a control MOSFET and a synchronous MOSFET with integrated Schottky diode.

It is optimized internally for PCB layout, heat transfer and driver/MOSFET timing.

Custom designed gate driver and MOSFET combination enables h
