IR38060MTRPBF
Synchronous buck regulator controller.
Product Description
The IR38060 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 IR38060 a space-efficient
solution, providing accurate power delivery for low
output voltage and high current applications.
The IR38060 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 IR38060 can also operate as a standard analog
regulator without any programming and can provide
current and temperature telemetry in an analog format
