3 Description
The TPS6030x devices are a family of switched-
voltage converters designed specifically for space-
critical battery powered applications.
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).
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 3× or 4× conversion
mode.
Output 1 (OUT1) can deliver a maximum of 40 mA
from a 1-V input, with output 2 (OUT2) not loaded.
OUT2 can deliver a maximum of 20 mA from a 1-V
input, with OUT1 not loaded. Both outputs can be
loaded at the same time, but the total output current
of the first voltage doubler must not exceed 40 mA.
For example, the load at output 1 is 20 mA and the
load at output 2 is 10 mA.
