[time-nuts] the care and feeding of LPRO's

[David VanHorn]

No, I haven't done this, but I realized this after fiddling around with
supplies and verified the ideas with a friend of mine designing supplies
all the time. He also pointed out that many switch supplies tend to run
better when the supply voltage is on the low side of things.


"Better"?  
Lower input voltage = higher input current.
Resistive losses in the primary side are R*I^2.. 
Lower input voltage = hotter, all other things being equal.
