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.
