IR3550 / IR3553 Integrated PowIRstage™

The International Rectifier PowIRstage integrates a high-performance synchronous buck gate driver with IR's latest generation control and synchronous MOSFETs, with low RDS(on) and gate charge, in addition to a Schottky diode. PowIRstage provides the industry's best 60 A rating with lower losses, higher efficiency, and excellent thermal management. PowIRstage simplifies the design and implementation of high-current, high-performance multi-phase buck regulators versus traditional discrete designs and alternative power stage solutions and is compatible with most analog and digital controllers on the market today.
