NOTE:
* 1: 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.
* 2: EFFI = {[(output voltage) x (output current)]÷[(input voltage) x (input current)] x 100
* 3: Applies to the XC6368 series only (duty ratio when control changes to PFM).
