The TPS51632-Q1 device is a driverless step-down controller with serial control. Advanced features such as D-CAP+ architecture provide fast transient response, lowest output capacitance, and high efficiency. The TPS51632-Q1 device supports both I²C and DVFS interfaces for dynamic control of the output voltage and current monitor telemetry. It also has dynamic phase add and drop control and enters single-phase, discontinuous-current-mode operation to maximize light-load efficiency.

The TPS51632-Q1 device supports Tegra requirements for PGOOD interrupts for MaxVID violations and near OCP conditions. This interrupt behavior is programmable via I²C. Adjustable control of V_CORE slew rate and voltage positioning round out the features. The TPS51604-Q1 driver is designed specifically for this generation of controllers. The TPS51632-Q1 device is packaged in a space saving, thermally-enhanced 32-pin VQFN and is rated to
