PowIRstage device achieves ‘industry’s highest’ current in smallest form factor
International Rectifier has introduced the first in a range of integrated PowIRstage products designed to deliver higher efficiency and better thermal performance than competing solutions. According to IR, the IR3550 is offered in the industry's smallest package and simplifies the dc/dc converter design for next generation high performance servers, storage and communication systems.
The 60A rated solution integrates a high performance synchronous buck gate driver, IR's latest control, synchronous MOSFETs and a Schottky diode into a high density, low profile 6 x 6 x 0.9mm PQFN package. The company claims it offers superior performance compared to alternative power stage solutions by achieving up to a 3% improvement in electrical efficiency to help reduce overall power losses and heat generation in the system.
Optimised for compatibility with most analogue and digital controllers available on the market today, the IR3550 features an integrated current sense amplifier which IR claims achieves superior accuracy and signal to noise ratios compared to alternate controller based inductor DCR sensing techniques.
