The TPS6013x step-up, regulated charge pump devices 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 and TPS60131, and 150 mA for the
TPS60132 and TPS60133 devices, all from a 3-V input. Only four external capacitors are required 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 1.5× or doubler
conversion mode. From a 3-V input, all ICs can start with full load current.
