Conditions: Unless otherwise stated, connect V DD to V OUT ; V IN =setting output voltage x 0.6, I OUT =130mA 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).
