Conditions: Unless otherwise specified, connect VDD to VOUT; VIN=setting output voltage x 0.6, IOUT=200mA
NOTE:
* 1: When taking VDD from another power source please ensure that VDD = 2.0V or more.
Oscillation will occur with a value of VDD = 0.8V or more, but with a value of VDD = 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).
* 4: The values of supply voltage and NOTE *1 do not apply to XC6367E/F and XC6368E/F series. For XC6367E/F and
XC6368E/F series, output voltage less than 2.0V cannot be set-up.
