IR3552MTRPBF

40A Integrated PowIRstage® FEATURES IR3552 DESCRIPTION • Peak efficiency up to 94.5% at 12VIN to 1.8VOUT, 93.3% at 1.2VOUT The IR3552 integrated PowIRstage™ contains a low quiescent current synchronous buck gate driver IC which is co-packed with control and synchronous MOSFETs and low side Schottky diode to further improve efficiency. The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing when layout guidelines are followed. The paired gate driver and MOSFET combination enables higher efficiency at lower output voltages required by cutting edge CPU, GPU and DDR memory designs. ® • 40A PowIRstage includes: Integrated Driver, Control MOSFET, Synchronous MOSFET and Schottky Diode •
