Description
General part information
TPS53679 Series
The TPS53679 is a fully VR13 SVID compliant step-down controller with dual channels, built-in non-volatile memory (NVM), and PMBus™ interface, and is fully compatible with TI NexFET ™power stage. Advanced control features such as D-CAP+™ architecture with undershoot reduction (USR) provide fast transient response, low output capacitance, and good current sharing. The device also provides novel phase interleaving strategy and dynamic phase shedding for efficiency improvement at different loads. Adjustable control of VCOREslew rate and voltage positioning round out the Intel®VR13™ features. In addition, the device 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.
The TPS53679 device if offered in a thermally enhanced -pin QFN packaged and is rated to operate from –40°C to 125°C.
