Product Brief PMBus SupIRBuck™ Voltage Regulators

Product Brief
PMBus SupIRBuck™ voltage regulators
IR3806x series (6 A/15 A/25 A/35 A)
The 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 the
family a space efficient solution, providing accurate power delivery for low output voltage
and high current applications.
