Simple battery circuit extends Power over Ethernet (PoE)
Articles  
2/3/2005   Post a comment
PoE power comes in the form of "48V at 350mA. If the PoE current is allowed to exceed 400mA, the standard calls for the PSE to break the circuit. This is a problem for devices that occasionally need a little more juice than PoE has to offer. Another problem is that "48V does not easily convert to commonly used positive voltage supply rails. Guess what: A Linear Technology engineer shows you how to do this from a battery.
