International Rectifier has introduced the IR3725 input power monitor IC with digital I2C interface for low-voltage DC/DC converters used in CPU, server and storage applications.
The device is a versatile input power, voltage and current monitor IC for 12 V power supplies.
Unlike other solutions that depend on A/D converters to measure a system’s power, this monitor uses 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, delivering current accuracy of 1.0%.
With a voltage accuracy of 1.5%, the device provides the option to use resistive sensing or inductor DCR current sensing with an internal thermal compensation feature to achieve high efficiency.
