description  
The TPS6013x step-up, regulated charge pumps generate a 5-V ±4% output voltage from a 2.7-V to 5.4-V input  
voltage (three alkaline, NiCd, or NiMH batteries or one Lithium or Lilon battery). The output current is 300 mA  
for the TPS60130/ TPS60131 and 150 mA for the TPS60132/ TPS60133, all from a 3-V input. Only 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 3-V input, all ICs can start with full load current.
