The TPS546C23 devices are PMBus 1.3 Compliant, non-isolated DC/DC converters with integrated FETs, capable of high-frequency operation and 35-A current output from a 7-mm × 5-mm package. Two TPS546C23 devices can be paralleled together to provide up to 70-A 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.
