Infineon’s digital multiphase and multi-rail controllers provide power for today’s medium and high current POL applications used in telecom/datacom and server & storage environments. Infineon’s digital controller family enables OEMs and ODMs to improve efficiency and total cost of ownership while increasing power density and optimizing the total system footprint of the voltage regulator. The PX7247, PX7241, PX7143, PX7242 and PX7141 are the first products out of our 4th generation digital controller family and support up to 2 rails with 1-6 phases on individual rails. The I2C/ PMBus interface connects the digital controllers to the application system and provides real time telemetry information, monitoring and control capabilities. The digital controllers are fully configurable through our POWERCODE™ graphical user interface that allows for easy to use and simplified design optimization.

Advantages of a digital controller

Protection features include a set of sophisticated over-voltage, under-voltage, over-temperature, and over-current protections. PX7247, PX7241, PX7143, PX7242 and PX7141 also detect and protect against an open circuit on the remote sensing inputs. These attributes provide a complete and advanced protection feature set for microprocessor, DSP, ASSP, FPGA or ASIC power systems. Accurate current sense telemetry is achieved through internal calibration that measures and corrects current sense offset error sources upon startup. Programmable temperature compensation provides accurate current sense information even when using DCR current sense.
