The TPS6012x step-up, regulated charge pumps

generate a 3.3-V or 3-V ±4% output voltage from  
a 1.8-V to 3.6-V input voltage (two alkaline, NiCd,  
or NiMH batteries). They can deliver an output  
current of at least 200 mA (100 mA for the  
TPS60122 and TPS60123), all from a 2-V input.  
Four external capacitors are needed to build a  
complete high efficiency dc/dc charge pump  
converter. To achieve the high efficiency over a  
wide input voltage range, the charge pump  
automatically selects between a 1.5x or doubler  
conversion mode. From a 2-V input, all ICs can  
start with full load current.

typical operating circuit  
The devices feature the power-saving pulse-skip  
mode to extend battery life at light loads.  
TPS60120, TPS60122, and TPS60124 include a  
low battery comparator. TPS60121, TPS60123,  
and TPS60125 feature a power-good output. The  
logic shutdown function reduces the supply  
current to a maximum of 1 µA and disconnects the  
load from the input. Special current-control  
circuitry prevents excessive current from being  
drawn from the battery during start-up. This dc/dc  
converter requires no inductors, therefore EMI is  
of low concern. It is available in the small,  
thermally enhanced 20-pin PowerPAD package  
(PWP).
