SLUSC39B June 2015 – February 2017 TPS53647
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 the NexFET power stages (CSD95372BQ5MC). The TPS53647 provides 8-bit BOOT 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 control features such as D-CAP+ architecture with undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance, and high efficiency. The TPS53647 also provides novel phase interleaving strategy and dynamic phase shedding for efficiency improvement at light loads. In addition, the TPS53647 supports 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 or PMBus and stored in non-volatile memory to minimize the external component count.
The TPS53647 is offered in a space saving, thermally enhanced 40-pin QFN package and is rated to operate from –40°C to 125°C.
