IR38063MTRPBF

IR38063MTRPBF is a 25A single-input voltage, synchronous buck regulator with PMBus interface. This IR38063 PMBus SupIRBuck™ is an easy-to-use, fully integrated and highly efficient DC/DC regulator with I2C/PMBus interface. The onboard PWM controller and MOSFETs make IR38063 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications. The IR38063 can be comprehensively configured via PMBus and the configuration stored in internal memory. In addition, PMBus commands allow run-time control, fault status and telemetry. The IR38063 can also operate as a standard analog regulator without any programming and can provide current and temperature telemetry in an analog format. Suitable for server applications, netcomm applications, embedded telecom systems and distributed point of load architectures.
