I'm looking for a transformer that is capable of stepping down 240V
from the wall outlet to maybe less than 20V depending on the type of
voltage regulator. My objective is to produce 3.3V from the wall outlet
to power my ICs.
1) Most of the times i see 2 same values for the secondary voltage, eg:
0-9,0-9 (9V). What does it mean? Does it mean i still get 9V output?
2) If i want to calculate the output current, do i take the power
rating lets say 3VA and divide with the output voltage, for example 3VA
/ 9V=0.33A?
