具有 NVM 和 PMBus VR13 的双通道 D-CAP+TM 降压多相控制器

制造商:TI

产品信息

描述The TPS53679 is a fully VR13 SVID compliant step-down controllerwith 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 withundershoot reduction (USR) provide fast transient response, low output capacitance, and goodcurrent sharing. The device also provides novel phase interleaving strategy and dynamic phaseshedding for efficiency improvement at different loads. Adjustable control ofVCORE slew rate and voltage positioning round out theIntel® VR13™ features. In addition, the device supports the PMBus communicationinterface for reporting the telemetry of voltage, current, power, temperature, and fault conditionsto the systems. All programmable parameters can be configured by the PMBus interface and can bestored in NVM as the new default values to minimize the external component count.The TPS53679 device if offered in a thermally enhanced-pin QFNpackaged and is rated to operate from –40°C to 125°C.特性Intel VR13 Serial VID (SVID) Compliant 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 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 PositioningPatented 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 CurrentAll trademarks are the property of their respective owners.
