Synchronous buck converters with PMBus and frequency synchronization

Capable of high-frequency operation and 20A or 30A current output from a 5mm × 7mm package - Digi-Key now stocks the Texas Instruments TPS544B25 and TPS544C25 PMBus 1.2 compliant, non-isolated DC-DC converters with integrated FETs. 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, says the company.
