The Infineon IR38064 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 IR38064 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications. The IR38064 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 IR38064 can also operate as a standard analog regulator without any programming and can provide current and temperature telemetry in an analog format
