sorry, last message was sent with wrong subject, please delete it :( --- Hi, is there a wonder-IC that will take 3.3V in input and give 5.0V in output w= ell filtered (similar to a linear voltage regulator output), and that doesn't r= equire many components? I was thinking about an integrated boost converter + LDO but the requiremen= t of an inductor plus n resistor and capacitors doesn't make me really enthusias= t. Maybe a more integrated IC? Or a charge-pump based one? Current requirement is low, 50mA would suffice. Do you know / can you suggest a nice and not too expensive IC which require= s as few external components as possible? I've searched but I am more lost than = before. Thank you very much.
