Input power monitor IC
International Rectifier has introduced the IR3725 input power monitor IC with digital I2C interface for low voltage DC-DC converters used in energy efficient cpu, server and storage applications.
The IR3725 is an input power, voltage and current monitor IC for 12V power supplies. The new device utilises IR's TruePower technology to output average power during a specified interval over a serial digital interface. This information is used by the system controller to optimise overall power consumption.
The IR3725 is a stand alone IC that measures power to optimise overall power consumption.
With a voltage accuracy of 1.5%, the IR3725 is said to provide design engineers with the option to use resistive sensing or inductor DCR current sensing with an internal thermal compensation feature to achieve efficiency while reducing component count and board size.
