DCS-ControlTM Topology  
step down DC-DC converter optimized for  
applications with high power density. A high switching  
frequency of typically 2.25MHz allows the use of  
small inductors and provides fast transient response  
as well as high output voltage accuracy by utilization  
of the DCS-Control™ topology.  
Input Voltage Range: 3 to 17 V  
Up to 500 mA Output Current  
Adjustable Output Voltage from 0.9 to 6 V  
Fixed Output Voltage Versions  
Seamless Power Save Mode Transition  
Typically 17µA Quiescent Current  
Power Good Output  
With its wide operating input voltage range of 3V to  
17V, the devices are ideally suited for systems  
powered from either a Li-Ion or other battery as well  
as from 12V intermediate power rails. It supports up  
to 0.5A continuous output current at output voltages  
between 0.9V and 6V (with 100% duty cycle mode).  
100% Duty Cycle Mode  
Short Circuit Protection  
Over Temperature Protection  
Available in a 2 × 2 mm, WSON-8 Package  
Power sequencing is also possible by configuring the  
Enable and open-drain Power Good pins.  
In Power Save Mode, the devices show quiescent  
current of about 17μA from VIN. Power Save Mode,  
entered automatically and seamlessly if load is small,  
maintains high efficiency over the entire load range.  
In Shutdown Mode, the device is turned off and  
shutdown current consumption is less than 2μA.
