The TPS6287Cxx devices are a family of pin-to-pin, up to 50A synchronous step-down DC/DC converters with I2C interface and differential remote sense. Low-resistance power switches allow up to 50A continuous output current at high ambient temperatures. The devices can operate in stacked mode to deliver higher output currents or to spread the power dissipation across multiple devices. In stacked operation, the converters frequencies are synchronized, share a common compensation signal and shift the phases to supply loads with several hundreds of amperes. The TPS6287Cxx family implements a fixed-frequency-DCS-Control scheme with adjustable switching frequency and adjustable loop compensation. The high switching frequency and loop bandwidth is optimized for low-profile- and small-size inductors and low output capacitance. Devices can operate in power-save mode (PSM) for maximum efficiency, or forced-PWM mode for best transient performance and lowest output voltage ripple. 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.
