1.5V to 5V Converter Schematic
In abounding cases can be actual accessible to be able to catechumen 1.5V to 5V. Then you can ability microcontroller or LED from a distinct AA or AAA battery. It is simple to do this as there are appropriate IC�s as MAXIM MAX1674 or MAX7176. This is addition DC-DC advocate that can catechumen voltages from 0.7V to any in ambit from 2V to 5.5V. MAX1676 accept already preset pins for 3.3V and 5V, that makes easer affiliation in 3.3 and 5V circuits. IC can blow up to 444mW.
