TPS53688 Step-Down Digital Multiphase Controllers

Texas Instruments TPS53688 Step-Down Digital Multiphase Controllers are fully VR13.HC SVID-compliant step-down controllers with two channels, built-in nonvolatile memory (NVM), and a PMBus™ interface. It is fully compatible with TI NexFET™ smart power stages. Advanced control features such as the D-CAP+™ architecture with undershoot reduction (USR) provide a fast transient response, low output capacitance, and good dynamic current sharing. The device also provides a novel phase interleaving strategy and dynamic phase shedding for efficiency improvement across loading conditions. Adjustable control of output voltage slew rate and adaptive voltage positioning is natively supported.
