Description
The TPS53647 is a high-current, multi-phase, step-down controller.The device offers built-in non volatile memory (NVM) and PMBus interface. It is compatible with theNexFET power stages (CSD95372BQ5MC). The TPS53647 provides 8-bitBOOT voltage selection covering output voltage from 0.5 V to 2.5 V, with steps as small as 5 mV,which is ideal for high current application with accurate output voltage setting. Advanced controlfeatures such as D-CAP+ architecture with undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance, and high efficiency. TheTPS53647 also provides novel phase interleaving strategy and dynamic phaseshedding for efficiency improvement at light loads. In addition, the TPS53647supports the PMBus communication interface with systems for telemetry of voltage, current, power,temperature, and fault conditions. Some of the configurations can be programmed by pinstrap orPMBus and stored in non-volatile memory to minimize the external component count.
The TPS53647 is offered in a space saving, thermally enhanced 40-pinQFN package and is rated to operate from –40°C to 125°C.
