PMBus voltage regulators

24 February 2016 Power Electronics / Power Management

Infineon Technologies introduced the PMBus SupIRBuck family of DC-DC regulators with I²C/PMBus interface. The integrated PWM controller, MOSFETs and bootstrap diode make them space-efficient solutions, providing accurate power delivery for low output voltage and high current applications. The devices can be comprehensively configured via PMBus and the configuration stored in internal memory. In addition, 75 PMBus commands allow precise run-time control, fault status monitoring and telemetry of parameters like Vin, Vout, Iout, T or Pout. They can also operate as a standard analog regulator without any programming, and can provide current and temperature telemetry in analog format.
