So I am new to electronics, but I'm trying to figure out if I can boost current from 10mA to 100mA. I researched and found a current booster called the lmc6001 that boosts from 10mA to 30, which is not what I need. Would I need a booster for this or is it possible with some components? It is also worth noting that I boosted my voltage with a step up voltage booster to 2.35v. So, I need something that is able to boost only current, is this possible?

    \$\begingroup\$ "I boosted my voltage" And that would be why you're getting so little current. \$\endgroup\$ – Ignacio Vazquez-Abrams Sep 4 '16 at 15:45

    \$\begingroup\$ You can't create power. Any circuit that increases current must also reduce voltage, or get power from an external source. \$\endgroup\$ – Peter Bennett Sep 4 '16 at 15:47

    \$\begingroup\$ Or sacrifice time for either of them. Technically it's energy you can't get more of, not power, but for most applications pulsing power is unsuitable. \$\endgroup\$ – Ignacio Vazquez-Abrams Sep 4 '16 at 16:01

    \$\begingroup\$ As stated above, unless you add another source of energy, there is no way to increase both. It is physically impossible, just like a perpetual motion machine. \$\endgroup\$ – DoxyLover Sep 4 '16 at 16:09

    \$\begingroup\$ draw a block diagram of what you want, including where you're going to get the extra power from (battery, power supply, whatever) and then we can suggest ways to do it. \$\endgroup\$ – Neil_UK Sep 4 '16 at 16:25

Buy a transistor. Use an emitter follower circuit. You will get a 0.7V voltage drop, but you will get all the current you need.

  • \$\begingroup\$ This is cool! Luckily, dropping .7v will not have any effect on the circuit, it actually makes it better because my 2.35v was already too high. I have one question though, could you explain what the collector is doing? \$\endgroup\$ – GC64 Sep 4 '16 at 17:10
  • \$\begingroup\$ collector is attached to supply voltage \$\endgroup\$ – Mark Ch Sep 4 '16 at 17:25

you can use this Ic too . this don't decrease your voltage and have perfect current boos like 10000 time grater but it need dual power supply the full name of Ic is:

((ADA4891-1))

and it's cost is lower than 0.5 $

  • \$\begingroup\$ Thanks, but unfortunately I can only have one power supply.. \$\endgroup\$ – GC64 Sep 4 '16 at 17:07
  • \$\begingroup\$ A 741 can't put out much more than 20mA, certainly not 100mA. \$\endgroup\$ – John D Sep 4 '16 at 17:15
  • \$\begingroup\$ ok but you can use it single now \$\endgroup\$ – saftargholi Sep 4 '16 at 17:35
