... Negative Terminal for C1 _______________Detailed Description Operating Principle The MAX619 provides a regulated 5V output from 3.6V (two battery cells) input. Internal charge pumps and external capacitors generate the 5V output, elimi- nating the need for inductors. The output voltage is regulated to 5V ± pulse-skipping controller that turns on the charge pump when the output voltage begins to droop ...
