Description
The TPS53622 is a fully VR13 SVID compliant step-down controller with dual channels, built-in nonvolatile memory (NVM), and PMBus™ interface, and is fully compatible with TI NexFET ™power stage.
Advanced control features such as D-CAP+™ architecture with undershoot reduction (USR) provide fast
transient response, low output capacitance, and good current sharing. The device also provides novel
phase interleaving strategy and dynamic phase shedding for efficiency improvement at different loads.
Adjustable control of VCORE slew rate and voltage positioning round out the Intel® VR13™ features. In
addition, the device supports the PMBus communication interface for reporting the telemetry of voltage,
current, power, temperature, and fault conditions to the systems. All programmable parameters can be
configured by the PMBus interface and can be stored in NVM as the new default values to minimize the
external component count.
The TPS53622 device if offered in a thermally enhanced -pin QFN packaged and is rated to operate from
–40°C to 125°C.

Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
