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.
