Measuring conditions:
When taking V
DD
from another power source please ensure that V
DD
= 2.0V or more.
Oscillation will occur with a value of V
DD
= 0.8V or more, but with a value of V
DD
= 2.0V or more,
output voltage and oscillation frequency will be stable.
Note 1:
EFFI = {[(output voltage) x (output current)]
÷
[(input voltage) x (input current)} x 100
Note 2:
Applies to the XC6368 series only (duty ratio when control changes to PFM).
Note 3:
There are no products within the XC6367E, XC6368E series range which have a set-up
voltage of less than 2.0V.
Note 4:
