EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced that its IR3725 power monitor IC is named in EDN magazine’s “Hot 100 Electronic Products for 2009”.

Compiled by EDN's editors, this annual listing highlights the electronics industry's most innovative and significant products, including analog and digital ICs.

Tim Phillips, vice president, IR’s Enterprise Power Business Unit, said: “The IR3725 is an easy to implement, highly configurable, stand alone IC that precisely measures power to optimize overall power consumption while significantly reducing total system cost. The device exemplifies our approach to delivering innovative, highly efficient solutions to the enterprise power market.”

The IR3725 is a highly versatile input power, voltage and current monitor IC with digital I²C interface for low-voltage DC-DC converters used in energy-efficient CPU, server and storage applications. Unlike alternative solutions that depend on costly A/D converters to measure a system’s power, the new device utilizes patent-pending TruePower™ technology to output average power during a specified interval over a serial digital interface. This information is used by the system controller to optimize overall power consumption, delivering benchmark current accuracy of 1.0 percent.

The IR3725 provides design engineers with the option to use resistive sensing or inductor DCR current sensing with an internal thermal compensation feature to achieve high efficiency while reducing component count and board size.
