I am unable to find any IC that would allow me to have 2 DC inputs (5v/12v coming from the PC psu) and have one of them as output (being either 5v out or 12v out). This is for power to a PC Fan that should, at the far end when using a 140mm case fan, would pull 4.2 to 6W. So around ~400mA...
I figured that a DPST switch would work but I'm not quite sure that is what I need for this?
Being hooked to a microcontroller (PIC), I would be able to switch from the default voltage (that being 5vdc) to the 12vdc and, if needed, back to 5vdc.
Anyone know of an IC that would work like this for my needed purpose? It would also be nice if the IC had 4 outputs (2 inputs) so that I wouldn't have to have so many of them on my PCB. I will have 8 4pin connectors so that would be a total of 8 outputs that I would need.
