Hello, just joined the forum to get some info on this.
Can the W5100 use an external 1.8V supply?
We have a design that needs to have the lowest power consumption as possible, and I’m wondering if we could save a little bit by using an external 1.8V supply. (It would be a buck (switching) regulator - more efficient than a linear type)
Even saving about 100mW would be good. (Need to meet minimum standby power requirements… )
If it’s possible, then, what sort of timing requirements are there? Like, does the 1.8V have to come up after the 3.3V, does it have to come up with a specific dv/dt, etc…
Looking forward to get some feedback!
