Product Description
Texas Instruments’ TPS544x25 devices are PMBus 1.2 Compliant, non-isolated SWIFT Synchronous Buck Converters DC-DC converters with integrated FETs, capable of high-frequency operation and 20A or 30A current output from a 5mm × 7mm package.
An integrated NexFET power stage and optimised drivers provide high-frequency, low-loss switching, enabling very high-density power solutions.
The PMBus interface enables the AVS through VOUT_COMMAND, flexible converter configuration, as well as key parameters monitoring including output voltage, current and an optional external temperature. Response to fault conditions can be set to either restart, latch-off or ignore depending on system requirements.
Typical applications include Test and Instrumentation, Ethernet Switches, Optical Switches, Routers, Base Stations, Servers, Enterprise Storage SSD and High-Density Power Solutions.
