--- Quote from: mariush on September 17, 2019, 02:11:46 pm ---There are switching regulators with up to 90-95% efficiency.... it may beat the losses caused by reducing 6v+ to 3.3v... again, it depends on power consumption of 3.3v device vs 6v device power consumption ... As for noise, you can always add extra filtering (pi filters) or boost by a bit more than 6v then use a very low drop regulator to bring down to 6v --- End quote --- That is true, but for someone in the beginners section who thought he should sum the voltages together to get 9.3V. He's clearly new to electronics and I don't think it's a good idea to complicate things too much. But it would be nice to know the power of the devices it would make it a lot easier for everyone to suggest appropriate things. |
