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.

The TPS546C23EVM1-746 evaluation module provides two separate buck converters that convert from a nominal 12-V bus to produce two regulated 0.9-V outputs, up to 35 A of load current each. The TPS546C23EVM1-746 is designed to demonstrate the TPS546C23 in a typical single-phase low output voltage (...)
The TPS546C23EVM2-746 evaluation module combines two 35-A TPS546C23 buck converters in a stackable configuration to deliver a continuous 70-A output current and a regulated 1.2-V output from a nominal 12-V input bus. The evaluation module accomodates the PMBus interface with telemetry.
