IR IR3721Using TruePower technology, International Rectifier’s IR3721 output power monitoring IC captures dynamic power information with 2.5% static accuracy at 65°C. The 10-pin lead-free DFN-packaged component works for DC/DC converters used in notebook computers, desktop computers, and energy-efficient server applications. The RoHS-compliant IC monitors power or current at the output/load side of voltage regulators. The device performs in the output filter inductor current in a buck or multiphase converter from 0.5 V to 1.8 V. Optional resistive sensing or inductor DCR current sensing with an internal thermal compensation feature is included.
