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