TPS544B25/C25 DC-DC Converters

TI's 4.5 to 18 V, 20 and 30 A, SWIFT synchronous buck converters with PMBus and frequency synchronization

Image of TI's TPS544x25 DC-DC ConvertersTexas Instruments' TPS544B25 and TPS544C25 devices are 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.
