LT8607-5 Internal Cff

jeams13 on May 15, 2025

Category: Datasheet/Specs

Product Number: LT8607

Could you please let me know the value of the internal feedforward capacitor (Cff) in the LT8607-5?
I would like to use it with adjustable LT8706 version when simulating in LTspice or LTpowerCAD.

LT8706 was a mistake. I would like to simulate the LT8607-5 using the adjustable LT8607 model and the internal Cff value.

Hi jeams13 ,

Not definitive, but the two apps in the datasheet appear to be interchangeable:

Hi,

Thank you for your reply.

According to the pin functions description, VOUT is connected to an internal 6.6 MΩ divider. So, assuming the same time constant as the 1 MΩ // 10 pF combination in the adjustable version, would the internal capacitor be more like 1.5 pF rather than 10 pF?
