If you are doing amps simulations
you will find SMPS having 40%, efficiency over 70% or 85%
Higher the better !!!
why this efficiency matters?
40% efficiency — It’ll get hot, and
waste heat.
What about output voltage?
will it be floating?
Efficiency and stability aren’t
necessarily related.
Will lower efficiency booster burn
out due to its heating?
it depends. For every 1 watt you put
in, you’ll get out 400mW, and 600mW will get burnt up as heat. If your
booster’s thermal design isn’t up to handling that heat with proper thermal
spreading or heat sinks, it’ll get too hot and burn up.
Also, the main disadvantage of low
efficiency is energy loss
A with low efficiency may also produce more EMI due to the higher current it requires. This may affect other circuits as well
