TPS53647RTAR Product Details

The TPS53647RTAR is a high-current, multi-phase, step-down controller.Thedevice offers built-in non volatile memory (NVM) and PMBus interface. It iscompatible with theNexFET power stages (CSD95372BQ5MC). The TPS53647RTAR provides8-bitBOOT voltage selection covering output voltage from 0.5 V to 2.5 V, withsteps as small as 5 mV,which is ideal for high current application withaccurate 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 highefficiency. TheTPS53647RTAR also provides novel phase interleaving strategy anddynamic phaseshedding for efficiency improvement at light loads. In addition,the TPS53647supports the PMBus communication interface with systems fortelemetry of voltage, current, power,temperature, and fault conditions. Someof the configurations can be programmed by pinstrap orPMBus and stored innon-volatile memory to minimize the external component count.

The TPS53647RTAR is offered in a space saving, thermally enhanced 40-pinQFNpackage and is rated to operate from –40°C to 125°C.
