描述The TPS53659 is a fullyVR13 SVID compliant step-down controller with dual channels,built-in non-volatile memory (NVM), and PMBus™ interface, and isfully compatible with TI NexFET™ power stage. Advanced controlfeatures such as D-CAP+™ architecture with undershoot reduction(USR) provide fast transient response, low output capacitance, and good current sharing. The devicealso provides novel phase interleaving strategy and dynamic phase shedding for efficiencyimprovement at different loads. Adjustable control of VCORE slew rate andvoltage positioning round out the Intel® features. In addition, the device supports the PMBus communication interface forreporting the telemetry of voltage, current, power, temperature, and fault conditions to thesystems. All programmable parameters can be configured by the PMBus interface and can be stored inNVM as the new default values to minimize the external component count.The TPS53659 device if offered in a thermally enhanced 40-pin WQFNpackaged and is rated to operate from –40°C to 125°C.特性Full VR13 Server Feature Set Including Digital Input Power MonitorProgrammable Loop CompensationsConfigurable with Non-Volatile Memory (NVM) for Low External Component Counts Individual Phase Current Calibrations and Reports Dynamic Phase Shedding with Programmable Current Threshold for Optimizing Efficiency at Light and Heavy Loads Fast Phase-Adding for Undershoot Reduction (USR)Backward VR12.0 and VR12.5 Compatible 8-Bit DAC with Selectable 5 mV or 10 mV Resolution and Output Ranges from 0.25 V to 1.52 V or 0.5 V to 2.8125 V for Dual Channels Driverless Configuration for Efficient High-Frequency Switching Fully Compatible with TI NextFET™ Power Stage for High-Density Solutions Accurate, Adjustable Voltage Positioning Frequency Selections with Closed-loop Frequency Control: 300 kHz to 1 MHzPatented AutoBalance™ Phase Balancing Selectable, 16-level Per-Phase Current Limit PMBus™ System Interface for Telemetry of Voltage, Current, Power, Temperature, and Fault Conditions Dynamic Output Voltage Transitions with Programmable Slew Rates via SVID or PMBus InterfaceConversion Voltage Range: 4.5 V to 17 VLow Quiescent Current 5 mm × 5 mm, 40-Pin, WQFN PowerPad™ Package All trademarks are the property of their respective owners.
