The TPS51386 is a monolithic, 8-A, synchronous buck converter with adaptive on-time D-CAP3 control mode. Integrated low R DS(on) power MOSFETs enable high efficiency and offer ease-of-use with minimum external component count for space-constrained power systems. Features include an accurate reference voltage, fast load transient response, auto-skip mode operation for light load efficiency, OOA light load operation with > 25-kHz switching frequency, D-CAP3 control mode with good line, load regulation, and does not require external compensation.

The TPS51386 provides complete protection OVP, UVP, OCP, OTP, and UVLO. The device is a combined power-good signal and output discharge function.

The TPS51386 supports both internal and external soft-start time option. The device has the internal fixed soft-start time 1 ms. If the application needs longer soft-start time, the external SS pin can be used to achieve longer soft-start time by connecting the external capacitor.

The TPS51386 are available in a thermally enhanced 12-pin QFN package and are designed to operate from –40°C to 125°C junction temperature.
