IR38064MTRPBF

IR38064MTRPBF is a PMBus SupIRBuck™ is an easy-to-use, fully integrated and highly efficient DC/DC regulator with I2C/PMBus interface. The on-board PWM controller and MOSFETs make it a space-efficient solution, providing accurate power delivery for low output voltage and high current applications. It 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. It can also operate as a standard analogue regulator without any programming and can provide current and temperature telemetry in an analogue format. Application includes server applications, netcomm applications, embedded telecom systems, distributed point of load architectures.
