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, Ni Cd, or Ni MH battery). Only five small 1-µF ceramic capacitors are required to build a plete 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 m A from a 1-V input, with output 2 (OUT2) not loaded. OUT2 can deliver a maximum of 20 m A 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 m A. For example, the load at output 1 is 20 m A and the load at output 2 is 10 m A.
