International Rectifier IR355x PowIRstage™ Buck Gate Drivers

International Rectifier IR355x PowIRstage™ Buck Gate Drivers

International Rectifier's IR355x PowIRstage™ Buck Gate Driver family of integrated devices utilize advanced silicon, packaging and control techniques, to integrate a synchronous buck gate driver, benchmark figure-of-merit control, and synchronous MOSFETs and Schottky diode into a small, high density, low profile package. These devices deliver a high current density and high efficiency power stage solution that simplifies the design and implementation of high current, high performance multiphase buck regulators.

Features
  • Peak efficiency up to 95.0% at 1.2V
  • Integrated driver, control MOSFET, synchronous MOSFET and Schottky diode
  • Input voltage (VIN) operating range up to 15V
  • Output current capability of up to 60A DC
  • Operation up to 1.0MHz
  • Efficient dual sided cooling

  • Small PQFN package
  • Lead free RoHS compliant package

Applications
  • Voltage Regulators for CPUs, GPUs, and DDR memory arrays
  • High current, low profile DC-DC converters
