LTM4624 - Clarification for Feedforward Capacitor

Category: Datasheet/Specs
Product Number: LTM4624

Dear Team,

I am using the LTM4624 micromodule regulator with a 5V input and a 0.7V output. As per the datasheet, a 10pF to 15pF feedforward capacitor (CFF) is recommended between the VOUT and FB pins for low output voltages.

However, I noticed that the DC1889A evaluation board uses a 100pF CFF.

Could you please confirm the recommended value of CFF for a 0.7V output in my case? Also, is there a formula or guideline to calculate the optimal CFF based on output voltage or other parameters?

Your clarification would be very helpful.

Thanks,

Mithun
