IR3742 Overview
The IR3742 integrated PowIRstage® is a synchronous buck gate driver IC with co-packed control and synchronous MOSFETs and Schottky diode. It is optimized internally for PCB layout, heat transfer and driver/MOSFET timing. Custom designed gate driver and MOSFET bination enables higher efficiency at lower output voltages required by cutting edge ASIC, FPGA and advanced controller.
