description

The TPS6031X step-up, regulated charge pumps

generate a 3-V ±4% or 3.3-V ±4% output voltage

from a 0.9-V to 1.8-V input voltage (one alkaline,

NiCd, or NiMH battery).

Only five small 1-μF ceramic 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 3x or 4x conversion mode.
