The TPS6014x step-up, regulated charge pumps  
generate a 5-V 4% output voltage from a 1.8 V  
to 3.6 V input voltage range. The devices are  
typically powered by two alkaline, NiCd, or NiMH  
battery cells and provide an output current of  
minimum 100 mA from a 2-V input. Only four  
external capacitors are needed to build a  
complete voltage tripler charge pump.

The devices regulate the output by using the  
pulse-skip topology. The controller is optimized for  
lowest output voltage ripple over the complete output current range. The output peak current and therefore the  
output voltage ripple are drastically reduced compared to a conventional pulse-skip topology by regulating the  
charge pump output resistance. At light loads the maximum output resistance is limited to assure a low  
quiescent current.  
The TPS60140 includes a low-battery comparator that issues a warning if the battery voltage drops below a  
user-adjustable threshold voltage. The TPS60141 features a power-good output that goes active when the  
output voltage reaches 90% of its nominal value.  
The logic shutdown function disables the converter, reduces the supply current to a maximum of 1 µA and  
disconnects the output 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 little  
concern. It is available in the small, thermally enhanced 20-pin TSSOP package (PWP).
