Conditions: Unless otherwise stated, VIN=1.8V, IOUT=120mA
External components : RFB1 = 400kΩ, RFB2 = 200kΩ, CFB = 47pF
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).
