I'm looking for a simple/easy DC converter 1V to 3.3V

[mabauti]

I was planning to implement it with a LMC555 , but it requires at least 1.5V

I need at least 25mA @ 3.3VCD

any ideas are welcomed

someone?

Use a simple Boost amplifier. You can read about it in just about any Power Electronics book. (Mohan's book for example).

For online references check:

Use chargepump based circuits. U can google and find related information.

I think your best choice is:MC34063.Very simple and very easy to use,also very cheap.

But I don't think that it will work for mabauti, because it's minimum supply voltage is +3V, and mabauti's supply voltage is only +1V.

Re:

Yep. I want to feed a 3.3V/ 3~12 mA circuit with a single 1.2 rechargeable battery
