7 Low-Voltage, High-Current, Core Rail Buck Converter

The TPS62893-Q1 is a synchronous step-down DC/DC converter with I2C interface and differential remote sense. The device can operate in stacked mode to deliver higher output currents or to spread the power dissipation across multiple devices. In stacked operation, the converter frequencies are synchronized, share a common compensation signal, and shift the phases to supply heavier loads. The I2C compatible interface offers several control, monitoring, and warning features including telemetry data of input voltage, output voltage, output current, and temperature. Four SET pins can be used to program default settings before start up.
