TPS546C20A PMBus Synchronous Buck Converters

Texas Instruments TPS546C20A PMBus Synchronous Buck Converters are PMBus 1.3 Compliant, non-isolated DC-DC converters with integrated FETs. Each is capable of high-frequency operation and 35A current output from a 5mm×7mm package. Two TPS546C20A devices can be paralleled together to provide up to 70A load. Current sensing is realized by sampling a small portion of the power stage current and independent on the device temperature. 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 functions through VOUT_COMMAND, flexible converter configuration, as well as key parameters monitoring including output voltage, current, and internal die temperature. Response to fault conditions can be set to either restart, latch-off or ignore depending on system requirements.
