DESCRIPTION  
The TPS6122x family devices provide a power-supply solution for products powered by either a single-cell,  
two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents  
depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic controller topology  
using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of  
the adjustable version can be programmed by an external resistor divider, or is set internally to a fixed output  
voltage. The converter can be switched off by a featured enable pin. While being switched off, battery drain is  
minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm x 2 mm to enable small  
circuit layout size.
