HI,

Customer finds overshopot during start-up, Cff would be added. However, this is fixed voltage version, how can I add the Cff? or is there another way to reduce overshoot?

Hi Alan,

You cannot add a Cff capacitor to the fixed output voltage option. Can you please provide a schematic and oscilloscope measurement showing Vin, Vout, and Ven?

Thanks,

Stephen
