3.3v convert 5v and vice versa
any IC can do this?
any schematic can provide to me? THXs |

At low currents there is probably a "charge pump" IC to do this, at higher currents you would need to build a DC-DC boost converter. The Maxim MAX1672 can do this at 300 or so mA. It is in a tiny package, but I am sure they have others parts in different packages.

Do you want to convert DC voltages (power supplies), or simply to convert between logic levels?

For Power supply,
actually, 5V to 3.3V |

I would use an LM317 setup to give 3.3V
Or make a voltage divider with resistors and add a emittor-follower (only good if input voltage is stable at 5V) Don't have any scematics handy right now... Maybe i'll find something to post later |
