International Rectifier has expanded its PowIRstage family of integrated devices with the 40 A IR3553, optimised for next-generation servers, consumer and communication systems.
Using the company's silicon, packaging and control techniques, the device integrates a synchronous buck gate driver, benchmark figure of merit control and synchronous MOSFETs and Schottky diode into a small, high density, low profile 6 x 4 x 0.9 mm PQFN package to deliver a high current density and high efficiency power stage that simplifies the design and implementation of high current, high performance multiphase buck regulators.
