Hi, Team
This is customer`s question.
I calculated values on based the equation (48)~(50) for the typical application of the datasheet.
Vout=3.3V, Gmod(fc)=0.542, gm(EA)=97uA/V, VREF=0.8, fp(mod)=1.5kHz, Cout=47uF, RESR=10mΩ
The result is following;
- Rc=3.3/(0.542*97u*0.8)=78.46kΩ (76.2kΩ)
- Cc=1/(2π*78.46kΩ*1.5kHz)=1352pF (2710pF)
- Cf=47uF*10mΩ/78.46kΩ=5.99pF (6.17pF)
The values inside the parentheses are the result of the datasheet.
Cc=1352pF or 2710pF
Which is correct?
Please teach me the calucuration of Cc/
Thanks and Regards,
