555 Charge Pump

Yesterday, Ronaldo commented on the Power Brick post pleading for a voltage doubler using the 555 chip. Well, since it sounded like it was an emergency, here you go. ;) D1-2 should be barrier Schottky diodes and don't forget the jumper under the IC.

    1. You would know what is the maximum current supplied by the "charge pump"

    2. It should get you close to 18v, though probably close to 17.

  5. Ty very much. Working with 1n4004 diodes. I had problems with used (salvage part) 555, but, with new ne555 works like it should.

  6. Will it work with 4.5v to 9v?

    1. I think that would depend on operating voltage range on your 555 chips. Check the data sheet.
