The TPS53632 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 TPS53632 device supports the standard I2C Rev 3.0 interface 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.

Other features include adjustable control of VCORE slew rate and voltage positioning. The TPS51604 device driver is designed specifically for this generation of controllers. In addition, the TPS53632 device can be used along with the TI power stage devices (driver MOSFETs). The TPS53632 device is packaged in a space saving, thermally enhanced, 32-pin VQFN package and is rated
