TPS53647 Buck Controller

4-phase, D-CAP+™ step-down buck controller with NVM and PMBus interface for ASIC from Texas Instruments

Image of TI's TPS53647 Buck ControllerTexas Instruments' TPS53647 is a high-current, multi-phase, step-down controller. The device offers built-in non-volatile memory (NVM) and PMBus interface. It is fully compatible with the NexFET power stage (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.
