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. 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: XC6367C, XC6368C series Series Amendments: Please note that the following condition applies : Soft Start Time (TSS) : Connect RSS, CSS. CE 0V 3.0V XC6367E, XC6368E series Please delete 'Supply Voltage (VDD) ' and '(Note 1)' Please add the following note : There are no products within the XC6367F, XC6368F series range which have a set-up voltage of less than 2.0V. Note 4: Please delete 'Supply Voltage (VDD) ' and '(Note 1)' Please add the following note : XC6367F, XC6368F series Please note that the following condition applies : Soft Start Time (TSS) : Connect RSS, CSS.
