TPS544B25RVFR Integrated Circuit Chip SWIFT™ Synchronous Buck Converters With PMBus™

TPS544B25RVFR Integrated Circuit Chip SWIFT™ Synchronous Buck Converters With PMBus™

Product Description Of TPS544B25RVFR
TPS544B25RVFR is PMBus 1.2 Compliant, non-isolated DC-DC converters with integrated FETs, capable of high-frequency operation and 20-A or 30-A current output from a 5 mm × 7 mm package. High-frequency, low-loss switching, provided by an integrated NexFET™ power stage and optimized drivers, allows for 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.
