Texas Instruments TPS53681 Multiphase Step-Down Controller

Texas Instruments TPS53681 Multiphase Step-Down Controller comes with dual channels, built-in non-volatile memory (NVM), and PMBus™ interface, and is fully compatible with TI NexFET™ power stage. The device includes advanced control features such as D-CAP+™ architecture with undershoot reduction (USR) provides a fast transient response, low output capacitance, and high efficiency. The TPS53681 also provides a novel phase interleaving strategy and dynamic phase shedding for efficiency improvement at different loads. The device supports fast dynamic voltage transitions with an adjustable slew rate. The TPS53681 also supports the PMBus communication interface for reporting the telemetry of voltage, current, power, temperature, and fault conditions to the systems. All programmable parameters can be configured by the PMBus interface and can be stored in NVM as the new default values to minimize the external component count.
