The TPS568230is a cost effective, high-voltage input, high efficiency synchronous buck converter with integratedMOSFETs.

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. Ituses DCAP3? control mode to provide fast transient response, goodline, load regulation, no requirement for external compensation, and support low equivalent seriesresistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramiccapacitors.

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

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

The TPS568230 supports both internal and external soft-start time option. The internalfixed soft-start time is 1.3 ms. Longer soft-start time can be get by connecting the externalcapacitor 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.
