IR38064 Synchronous Buck Regulator with PMBus Interface
12V Single supply in Analog Mode
The 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.
