Hi All,
Let me ask about Cff for DCDC1. You recommend Cff = 47pF for all output voltage setting. I know it should be adjust to set Fz to optimize phase margin. Then can you provide the recommended Fz range? I calculated Fz by using divider and Cff in Table.3 in datasheet, then it set to around 6kHz for Vout >= 2.5V, and 11kHz for Vout <= 1.8V.
Your comment will be appreciated.
