Power Stage Solution Achieves High Current in Small Form Factor
The 60A rated IR3550 simplifies the design and implementation of high current high performance multiphase buck regulators. The resulting system solution helps enable fewer phases and lower cost compared to alternative solutions.
The new PowIRstage solution integrates a high-performance synchronous buck gate driver, IR’s latest generation control, and synchronous MOSFETs featuring extremely low on-state resistance (RDS(on)) and gate charge, and a Schottky diode into a high density, low profile 6 x 6 x 0.9 mm PQFN package. The IR3550 offers superior performance compared to alternative power stage solutions, by achieving up to a 3 percent improvement in electrical efficiency to help reduce overall power losses and heat generation in the system, thereby reducing dependency on complex thermal management techniques and associated costs as well as improving reliability.
