3 Description
The TPS568231 is a small, high-efficiency,
synchronous buck converter with an adaptive ontime
D-CAP3 control mode. Because external
compensation is not required, the device is easy
to use and requires few external components. The
device is well-suited for space-constrained data
center applications.
The TPS568231 has competitive features including
a very accurate reference voltage, fast load
transient response, and no requirement for external
compensation, adjustable current limit, and both Ecomode
and FCCM operation modes for selection at
light-load condition through configuration of MODE
pin. To attain high efficiency at light load, Eco-mode
can be selected. To support tight output voltage ripple
requirement, FCCM can be selected. The TPS568231
operates from –40°C to 125°C junction temperature.
