2.5 V to 6 V Input Voltage Range  
DCS™ Control  
synchronous step down converter optimized for small  
solution size, high efficiency and suitable for battery  
powered applications. To maximize efficiency, the  
converter operates in PWM mode with a nominal  
switching frequency of 2.8 MHz/1.4 MHz and  
automatically enters Power Save Mode operation at  
light load currents. When used in distributed power  
supplies and point of load regulation, the device  
allows voltage tracking to other voltage rails and  
tolerates output capacitors ranging from 10 µF up to  
150 µF and beyond. Using the DCS™ Control  
topology the device achieves excellent load transient  
performance and accurate output voltage regulation.  
95% Converter Efficiency  
Power Save Mode  
20 µA Operating Quiescent Current  
100% Duty Cycle for Lowest Dropout  
2.8 MHz/1.4 MHz Typical Switching Frequency  
0.8 V to VIN Adjustable Output Voltage  
Fixed Output Voltage Versions  
Output Discharge Function  
Adjustable Softstart  
The output voltage start-up ramp is controlled by the  
softstart pin, which allows operation as either a  
standalone power supply or in tracking configurations.  
Power sequencing is also possible by configuring the  
Enable and Power Good pins. In Power Save Mode,  
the device operates at typically 20 µA quiescent  
current. Power Save Mode is entered automatically  
and seamlessly maintaining high efficiency over the  
entire load current range.  
Two Level Short Circuit Protection  
Output Voltage Tracking  
Wide Output Capacitance Selection  
Available in 3x3mm 16 Pin QFN Package
