TPS6122x Low Input Voltage, 0.7V Boost Converter With 5.5μA Quiescent Current  
1 Features  
3 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.

Up to 95% Efficiency at Typical Operating  
Conditions  
5.5 μA Quiescent Current  
Startup Into Load at 0.7 V Input Voltage  
Operating Input Voltage from 0.7 V to 5.5 V  
Pass-Through Function during Shutdown  
Minimum Switching Current 200 mA  
Protections:  
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.
