The TPS6030x 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).
ACTUAL SIZE
3,05 mm x 4,98 mm
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.
