The TPS568230 is a cost effective, high-voltage input, high efficiency synchronous buck converter with integrated MOSFETs.

The TPS568230 has the ULQ™ (Ultra Low Quiescent current) feature to enable low-bias current. It operates with supply input voltage from 4.5 V to 18 V. It uses DCAP3™ control mode to provide fast transient response, good line, load regulation, no requirement for external compensation, and support low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors.

The TPS568230 provides complete Over-voltage, Under-voltage, Over-current, Over-temperature and Under-voltage lock-out protections. It is combined power good signal , output discharge function and large duty operation feature.

TPS568230 is equipped with a MODE pin to select the desirable mode of operation. To attain high efficiency at light load, OOA mode and Advanced Eco-mode™ could be selected. OOA mode will not allow the part to go below audible frequency ( below 25kHz switching frequency ). FCCM is also available to support tight output voltage ripple requirement.

The TPS568230 supports both internal and external soft-start time option. The internal fixed soft-start time is 1.3 ms. Longer soft-start time can be get by connecting the external capacitor on SS pin.

The TPS568230 is available in a 20-pin 3.0-mm x 3.0-mm HotRod™ package and the junction temperature is specified from -40oC to 125oC.
