SLUSC39B – JUNE 2015 – REVISED FEBRUARY 2017 TPS53647 4-Phase, D-CAP+, Step-Down, Buck Controller with NVM
and PMBusв„ў Interface for ASIC Power and High-Current Point-of-Load
1 Features 3 Description The TPS53647 is a high-current, multi-phase, stepdown 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 …
