The TPS544B20 and TPS544C20 devices are PMBus compatible, non-isolated DC-DC Integrated FET converters, capable of high-frequency operation and delivering 20-A , or 30-A current output from a 5 mm × 7 mm package, enabling high-power density and fast transient performance with minimal PCB area. The PMBus interface provides for converter configuration as well as monitoring of key parameters including output voltage, current and an optional external temperature. High-frequency, low-loss switching, provided by an integrated NexFET power stage and optimized drivers, allows for very high-density power solutions and reduced inductor and filter capacitor sizes. Response to fault conditions can be set to either restart or latch off depending on system requirements.

The TPS544B20EVM-634 is designed to help the user easily evaluate and test the operation and functionality of the TPS544B20 buck converter. The EVM converts a 4.5-V to 18-V input voltage to a regulated 1.0-V output voltage that delivers up to 20 A in a 5-mm x7-mm QFN package. The output voltage on (...)
Fusion Digital Power™ graphical user interface (GUI) software is used to configure and monitor select Texas Instruments digital power controllers and sequencer/health monitors. The application uses the PMBus protocol to communicate with the device over serial bus by way of a TI USB adapter.
The MSP Power Management Bus (PMBus) embedded software library is a free C library for enabling PMBus master implementation on MSP microcontrollers that have eUSCI/USCI serial communication peripherals. In addition, the library supports alert response (for host notification in the presence of (...)
The Linux driver supports PMBus controlled Buck Controllers. The Linux driver supports communication through the PMBus and interfaces with the HWMon framework.
