International Rectifier IR3551 integrated device
International Rectifier has extended its PowIRstage family of integrated devices with the introduction of the IR3551, optimised for use in next-generation servers, desktop PCs, graphics cards and communication systems.
Offering a maximum operating point of 50 A, the device is optimised for high-end processor and DDR memory multiphase solutions, offering a peak efficiency of 94.5% at 1.2 V output. The device integrates a synchronous buck gate driver, benchmark figure-of-merit control and synchronous MOSFETs and a Schottky diode into a small, high-density, low-profile 6 x 5 mm footprint compatible PQFN package.
