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 VCORE 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
