The TPS7H5101 is a dual phase D-CAP+ buck controller. The controller is optimized for high current, point of load power delivery due to the advanced control features of the D-CAP+ architecture which support a fast transient response with low output capacitance and high efficiency. The output capacitance can further be minimized through both the use of droop regulation and by utilizing the configurable undershoot reduction (USR) feature.

Single or dual phase operation is possible with a single controller, thereby enabling power stage optimization for different current levels.

Multiple configuration options are possible with this controller. PMBus provides the option to enable or disable the controller along with dynamically change the output voltage ±10% (voltage margining). Additional features include differential remote sensing for accurate voltage regulation and configurable compensation for an optimized control loop.
