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...
