The MAX619 step-up charge-pump DC-DC converter provides a regulated 5V±4% output at 50mA temperature. The input voltage range is 2V to 3.6V (two batteries). The complete MAX619 circuit fits into less than 0.1 square inches of board space because only four external capacitors are required: two 0.22mF flying capacitors and 10mF on the input and output capacitors. Low operating c...

The LTC®1986 is a micropower charge pump DC/DC converter that supplies power to a 3V or 5V GSMSIM. It works in three modes: VOUT=5V (5V mode), VOUT=VIN (3V mode) or shutdown. Parts with an input voltage range of 2.6V to 4.4V can provide 10mA of output current. The LTC1986 allows a 2.6V drop at VIN, providing enhancements in 3V mode. In 3V mode, VOU...
