Exponential growth in the requirements for higher current at lower operating voltages has created a rough road for designers of DC-DC power management systems. International Rectifier has focused the power semiconductor industry's largest R&D effort to implement a roadmap for high performance and cost-effective DC-DC power management. IR's extensive discrete and IC portfolio makes IR the only power semiconductor company with a product for every power management socket on today's computing PCB. IR DC-DC solutions extend to telecom, datacom, networking and peripherals requirements.
