3 Description
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.
