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: XC6367D, XC6368D series Series Amendments: Please note that the following condition applies : Soft Start Time (TSS) : Connect RSS, CSS. CE 0V 3.0V 04S_02XC6367/68 02.09.12 14:41 ページ 415 |
