Overview

The TPS51386 is a monolithic, 8-A, synchronous buck converter with adaptive on-time D-CAP3 control mode. Integrated low RDS(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, autoskip mode operation for light load efficiency, OOA light load operation with >25-kHz switching frequency, DCAP3 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.
