Easy to use and highly efficient synchronous buck converter

The Texas Instruments TPS56C231 is a small, high-efficiency, synchronous buck converter with an adaptive on-time D-CAP3 control mode. As external compensation is not needed, the device is simple to use and needs few external components. The device is ideal for space-constrained data centre applications.

The device has competitive features comprising a very accurate reference voltage, fast load transient response, and no need for external compensation, adjustable current limit, and Eco-mode and FCCM operation modes for selection at light-load condition through the configuration of the MODE pin. To achieve high efficiency at light load, Eco-mode can be selected. To support tight output voltage ripple requirement, FCCM can be selected.

The device operates from a –40C to 125C junction temperature range.
